Question about printer
by Ivan Arteaga 30 Oct '06

30 Oct '06

Hello List, I have centos 4.3 and a printer Xerox4517 attached to it via parallel port. The problem I have is after some while of inactivity I cannot print, and when I check in the control center (KDE) I see the printer status is stopped (accepting jobs). I just have to start the printer and I can get it back to normal. It is possible to configure some kind of keep alive or something like that in order the printer doesn't go to the stopped state? I will appreciate your comments, --Ivan.

DomainKey and mailing list
by Aleksandar Milivojevic 30 Oct '06

30 Oct '06

Hm, my previous post on subject seem to have fallen in /dev/null (can't find it even in list archives, strange). Anyhow. While on the subject of spam control. I was playing lately with Domain Key (and also newer Domain Key Identified Mail) systems. It's currently primarly used by Yahoo and Google Mail (gmail). For example, all emails from gmail.com on this list have DomainKey-Signature header. Also, all of those emails fail the verification. It is most likely due to the mailing list mangling the Subject line (addtion of [CentOS] tag) and body of the message (addtion of footer). Currently, Google uses "in testing flag" in the DNS record (as can be seen from output of "dig beta._domainkey.gmail.com txt"), so none of those emails should be rejected by anti-spam software. However, if they change the flags to instruct anti-spam software to reject emails with invalid signatures, the emails from this (and many other) mailing lists will start bouncing big time. I guess if these systems become widespread in the future, either the mailing list will need to be updated (so that it regenerates signatures with its own key, as defined in proposed standards) or mangling of subject line and the body will have to be abandoned... Maybe it's a good time to start preparing for the possible future. -- NOTICE: If you are not intended recipient, you are hereby notified that by reading this message you agreed not to disturb frogs during mating season.

Terminal settings question.
by David Mackintosh 30 Oct '06

30 Oct '06

Hiya folks, Maybe someone can help me with this question. I'm a long time mutt user. However in recent years, I have been a member of an increasing number of mail lists. And an increasing number of mail list users are starting to use special characters in their emails that my terminal is not understanding correctly. When it doesn't understand the character correctly, it starts to interfere with the repaints when I scroll around through messages or through the indexes. As an example, I believe it was this list where there was recently a discussion regarding Core Duo which included a fancy symbol for (tm) in the subject line. This thread was the straw that broke the camel's back so to speak and I'm now an unhappy Thunderbird user as opposed to a happy mutt user. So. Clearly I have something set incorrectly so that Mutt (and/or the terminal I am using) do not understand the special characters. Can anyone point me in the right direction to find the answer as to how to fix this so that I can ditch Thunderbird and go back to Mutt? Thanks for your time. -- -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com

Booting kernel for installation CD
by termeau sebastien 30 Oct '06

30 Oct '06

Hello, I want to install CentOS 4.4 on a Compaq Proliant DL 360. The installation fails just after booting on the first CD. Linux tries to autodetect hardware and fails with the CDROM. Here is the error message: ########################## hdc: CD-224E, ATAPI CD/DVD-ROM drive Using cfq io scheduler ide1 at 0x170-0x177,0x376 on irq 15 ide-cd: cmd 0x5a timed out hdc: lost interrupt ide-cd: cmd 0x5a timed out hdc: lost interrupt CDROM 24x .... ide-cd: cmd 0x25 timed out ########################## I can install a RHEL4 ES on the same server whitout problem. I noticed that CentOS and RHEL use 2 different kernels to boot the 1st CD (in isolinux folder). So I tried to replace the CentOS kernel with the one I found on RHEL CD. And it works, the kernel boots, but my CentOS CD is not recognize anymore as a CentOS CD. Why CentOS didn't recognize my CDROM? What should I modify in order to install CentOS using the RHEL kernel? Thanks -- Virtue is its own punishment. - Aneurin Bevan

laptop power management problems
by Aleksandar Milivojevic 30 Oct '06

30 Oct '06

I've a "small" problem with returning from suspend mode on my laptop. Under Windows XP, it works perfectly. Under CentOS, it simply freezes. The thing I'm suspecting is the hard drive not spinning. Has anybody else experienced same problem, and/or have some advice? I hoped hdparm might have something usefull, but reading the man page I haven't found anything promising to try out. Another thing I attempted is to recompile kernel with support for user mode suspend (or something like that) that I heard should work very nicely (not dependent on BIOS or anything, purely implemented in Linux). However, the rebuild of centosplus kernel with that option enabled simply failed with bunch of errors. It's an older laptop that uses APM (no ACPI). I'm not sure what debugging information might be helpfull. Kind of clueless here. I'll be happy to provide any information needed though.

28 Oct '06

Hey Group, We are trying to build a shared disk, shared cpu, shared ram....using a dell power edge servers.....which can utilize our server resource for our expanding website. We are running RHEL4 on dell power edges. Can anyone suggest any good production ready open source solution running on top of 2.6 kernel that might work for us? I have looked at openMosix which has only 2.4 kernel production ready and openSSI which has only 1.2 tested on 2.4 kernel and 1.9 still in testing. Is there any solution which can work with 2.6 kernel. Also IF POSSIBLE we would like to integrate the solution with Xen3.0.2. Can anyone suggest us a good open source solutions which migh work in our case? Thanks a lot. Regards, Saptarshi Naha

Need help - Install Driver for Video Capture Card
by Ahmad Ridhwan Wahap 28 Oct '06

28 Oct '06

Hi everybody, I need help to install driver for video card. I have physically installed two video capture card on two different computers. Both running Linux CentOS release 4.4 (final), and kernel 2.6.9-42.0.3.ELsmp. The first computer is Pentium D 3.00 GHz, 1Gbyte RAM. The second computer is AMD Athlon 2800+, 1 Gbyte RAM. I succesfully installed opencv-0.9.7 on both computers with gtk+ 2.x, libjpeg, zlib, libpng, libtiff, ffmpeg, dc1394, raw1394 and V4L pre-installed. Opencv running very well on both computers. I installed Hauppauge ImpactVCB (model 558) on Pentium D machine, while on Athlon machine, I installed I-O Data GV-VCP2M/PCI. After physically installing the cards, I installed the bttv-0.9.15 driver on both machine according to the instru8ction given by : http://www.faqs.org/docs/Linux-mini/BTTV.html, with exception that I did not recompile the kernel as instructed if the machine does not has the videodev.o, bttv.o, and tuner.o. Both machines do not have the files mentioned above. After completed installation, I could capture videos through the cards on both machines. However, if i restarted the machines, I could not capture any video anymore. I have to repeat the process of loading the modules as follow: - sync; sleep 1; sync - modprobe videodev - modprove bttv Would anyone help me solve this problems. I already write in the modprobe.conf file the following: Pentium D machine: alias char-major-89 i2c-dev options i2c-core i2c=debug=1 options i2c-algo-bit bit=test=1 alias char-major-81 videodev alias char-major-81-0 bttv option bttv card=10 Athlon machine: alias char -majorp-81 alias char-major-81 bttv options bttv card=2 I really do not remember where I got the codes, and I also not very sure whether they are correct or not. I'm quite new in this. Thank you in advance for your help. regards, arw_opencv --------------------------------- What will the world find in 2020? Leave a part of your 2006 in the Yahoo!

Hyperthreaded CPU and SMP kernel
by fredex 27 Oct '06

27 Oct '06

Hi gang! I'm using Centos 4.4 at work on a HP Proliant DL320 G2, which has a Hypterthreaded Pentium IV CPU. I used to use RHEL WS 2.1 on it, and RH installed and used the SMP kernel. Centos 4.4 did NOT install the SMP kernel. Is there some reason why I should NOT install it myself? I.e., some reason why an SMP kernel shouldn't be used on such a machine?

AACRAID controller setup?
by Les Mikesell 27 Oct '06

27 Oct '06

This isn't exactly a Centos question but maybe someone here can help: Does the AACRAID controller (as in an IBM 3550) store its config info on the drives or internally? I only have one of the boxes and want to load Centos 3.x on several drives which can be swapped into servers at another location. With SCSI, all that took was a full disk dd copy and a little fiddling with the HWADDR for the nics. However these don't even see a disk until you run the raid setup in bios. Does anyone know if a new server will recognize the setup (one drive, no raid) from the cloned disk or what it will take to make it accept the swap? -- Les Mikesell lesmikesell(a)gmail.com

Experiences with CentOS & MacBook Pro?
by Benjamin Smith 27 Oct '06

27 Oct '06

Ok, I'm finally of a mindset to replace my now tired, aging Dell Inspiron 600m. I'm currently running Fedora Core on it, and am fairly happy with the software. Has anybody used CentOS on a Macbook Pro? What gotchas are there? (The first that comes to mind is the lack of a right mousebutton) Scouting on the Internet, I've seen that some people have trouble getting sound to work. I'm interested in the following: 1) Network/Wifi support 2) Sound 3) Video (don't need 3D, currently using 2D ATI Radeon drivers and am happy) 4) USB support (works?) 5) External video - I frequently have to give presentations!

seamonkey and new command mozilla-xremote-client
by Jerry Geis 27 Oct '06

27 Oct '06

All, For 4.4 mozilla is out and seamonkey is in. In the old mozilla there was no command mozilla-xremote-client. In the new seamonkey there is a command mozilla-xremote-client. Under mozilla you could do "mozilla -remote "openurl(www.cnn.com)" and it would set the current page to the url. Trying this under seamonkey does not work. however, I just found the new command mozilla-xremote-client that does work now for seamonkey. My question is the command is only /usr/lib64/mozilla-seamonkey-1.0.5/ this directory and /usr/lib64/mozilla* has mozilla mozilla-1.7.12 mozilla-seamonkey-1.0.3 mozilla-seamonkey-1.0.5 Is it an oversite that the mozilla-xremote-client is not in the "normal" bin places? After updates I can manually go out to machines and change sym links or anything how can a sym link automatically be updated to the new mozilla-xremote-client after a yum update? Thanks, Jerry

Any time you have a "backup mx" server that does not do recipient validation for the domains it serves not only is it going to receive a lot of spam, it is going to be producing a lot. This is exactly the type of thing that lands IP addresses in blacklists in my experience. That being said you should be able to whitelist the IP of the blacklisted host before you do the rbl-checking. I know how to do this with postfix but not sendmail. I am not a sendmail user, but there are some sendmail users on the list who may be willing to help there. My guess is that if you post to the mailing list of the MTA in question you may raise their ire a bit as you seem to be trying to solve a problem further downstream than you should be (idiots on your network).

ISA sound cards and stuff
by Aleksandar Milivojevic 27 Oct '06

27 Oct '06

I've created kernel-isa and kernel-isasmp packages (currently i586, there'll be i686 version soon too). Basically, it is centosplus kernel with ISA Plug and Play, ISA and PCMCIA sound cards and ISA network cards enabled. The change to kernel spec file to add these two packages was fairly simple, and I hope this might find the way into centosplus kernel. If maintainer(s) of centosplus kernel are interested, I can email the patch for the spec file and four additional kernel config files. I've tested it on my old laptop that has built-in ISA sound card (ESS ES1878). Kudzu and automatic sound card detection didn't work, however after I manually added entries to /etc/modprobe.conf, it all worked nicely. I had to manually specify io, irq, and dma settings in the options line, and I guess the same may be true for most ISA hardware. I don't really have anything Plug and Play to test, and no ISA network cards anymore. Anyhow, if anybody does have, it would be nice if (s)he could test if all works OK. The Plug and Play is in kernel, no userland tools should be needed (hopefully). The only sound card missing is Wavefront. The source code for device driver needs some updating (there seem to be a patch floating around somewhere though, haven't tested it yet). The way it is now, it produces unresolved symbols if compiled. I see these packages mostly useful for folks with older laptops (ISA based sound cards, buying cheap PCI card is no option on laptops). Also for folks with older motherboards that have run out of PCI slots, but still have a few free ISA slots. The packages are signed with my PGP key (same as the one used for this email, you can grab it from most PGP key servers). Key fingerprint is 46FE 7D24 2D50 566A FBF3 7395 4AE4 9AE0 D660 AA3F or something like that. The URL is http://www.milivojevic.org/linux/rpm/el4/i386/

which http proxy to choose
by Mindaugas 26 Oct '06

26 Oct '06

Hello, Which http proxy to choose nowadays? Squid? But as far as I understand it is single process which sounds not too effective for current dual cpu dual core servers. Apache? Something else? Load can reach 1000-1500 simultaneous but slow speed connections (mobile phone clients). From more advanced features I need just possibility to redirect requests to certain domains to another proxy. Thanks, Mindaugas

vmware, rhel4(or us) problems w/virtual usb ports
by rado 26 Oct '06

26 Oct '06

I ran across this and glad I did...saved my .10 worth of sanity I got left: It came from: http://kb.vmware.com/KanisaPlatform/Publishing/612/774_f.SAL_Public.html Guest Cannot See USB Device on RHEL4-x64 Host This problem was identified on VMware Server, but may affect other VMware products. When you connect a USB device to a host running the RHEL4-x64 operating system, then try to access the USB from the VMware guest, the following error message appears: The Existing driver (usbhid) could not be successfully disconnected. (operation not permitted) Unload the driver manually then try again <OK>. In this situation, you cannot unload the driver manually from the host, because it does not exist as a module—it is compiled directly into the RHEL4-x64 kernel. Normally, this situation is not a problem for VMware software, but the kernel does not support the required ioctl (control device) function to allow VMware to disconnect the device from the usbhid driver. As a workaround, you can recompile the host's kernel with usbhid as a module, then manage its removal with rmmod. However, because the usbhid driver is necessary to allow the host and guest operating systems to interact with a USB mouse and keyboard, removing the module from the recompiled kernel may not be appropriate for your system. You may need to use an upgraded kernel or a different operating system instead. thx John Rose

CentOS - Spam List?
by John Hinton 25 Oct '06

25 Oct '06

The latest thread on Spam on the list has the potential of dominating the list for a long time. Is there any chance that perhaps the CentOS team might consider an Anti-Spam for CentOS mailing list? I would love to participate in such a list. From a subscriber point of view, I would think a 'CentOS A/S' list would be both pertinent and manageable from a volume standpoint. I know this is a bit to the side, but really for many of us sysadmins, Spam is much harder to deal with than any other single portion of running a CentOS server. Are there any others that might like such a list? Would the CentOS team consider adding this mailing list? Best Regards, John Hinton

While I have had a couple of mailservers that were sending legitimate mail complain about this (greylisting all mail), the vast majority have had no problem with it. I use the postgrey script (has it's own yum repo too :) and after a 5 minute delay the first time a triplet (client/sender/recipient) is seen it is auto-whitelisted. And the greylisting happens after all sanity checks and rbls. Vastly reduced spam from spambots which tend to just blast the mail out with no concern for the response. But I only have 200+ mailboxes and around 15-20k emails a day, so YMMV. I think the bottom line is that you have to pick your MTA/Content filter and then get on the mailing list and pay attention. It's an on-going war and there is no set-it and forget-it. alex

This is well worth checking out and I would guess that any well-maintained MTA would support this type of thing. So your rbl checks/helo checks/hostname and mx checks happen before the mail is received. This greatly reduces the amount of processing time on the MTA and allows it to handle far more mail in these spam-predominant times. You don't want to block most of your spam with a perl script IMHO. On our MTA, between the aforementioned and greylisting we block enough spam for it to be manageable on the back end with very, very few false-positives and close to zero maintenance. I'm sure that if we wanted to block more we could spend a lot more time setting up traps/writing SpamAssassin rules etc. But we're quite happy with this setup. FYI, rbls we use are: relays.ordb.org list.dsbl.org sbl-xbl.spamhaus.org <-- best one dul.dnsbl.sorbs.net the last being the only one I've seen any false positives on and only 2 since we set it up. YMMV. alex

Just some new bogus spammer that cant get the protocol right or is the server under attack? I have googled around but cannot fins any answer or I just suck at googleing... Any ideas ?

detecting ECC errors?
by Christian Nygaard 25 Oct '06

25 Oct '06

How do you detect ECC memory errors when CentOS is booted? Just had a strange hardware error where a server machine hang during anaconda install it passed memtest86 test but the bios dmi log showed dimm bank 1b had failures. Now I wonder what would happen if a machine running in production would get such problems, how do you detect it without having to go into bios? Hints on what to use? Chris

Gnome's profiles tool?

Hi all, I'm looking for a tool to create and manage the users' profiles in GNOME desktop environment. I've searched Pessulus (included in GNOME admin tools by default according GNOME docs) whitout success. I've tried to compile Sabayon (the CentOS rpm is not avaiable I think) but there are a lot of dependencies to resolve. ¿Any ideas?

Help request...recovering LVM on centos 4.2
by Sanjay Arora 24 Oct '06

24 Oct '06

I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot with knoppix live cd and recover data through rsync. Knoppix is not automatically recognizing lvm partitions. My query is to ask for step by step instructions on finding & mounting my lvm partitions correctly using knoppix or installing earlier hdds one by one in the new file-server & restoring data to users. Pointers on any howtos or detailed examples of recovery would also be appreciated. With best regards. Sanjay.

DMA disabled on SATA disk with Core Duo/i955 machine (Inspiron 6400)
by first last 24 Oct '06

24 Oct '06

I am trying to use CentOS 4 on this machine and it does not allow me to set DMA to 1, it just says that it is not possible. I have tried updating to the latest release and it still won't work. I have searched for it on Google and there is a thread mentioning the same machine and CentOS, but none of the solutions (-p, -X 12) seem to work at all and there is no "it works!!!!!" message. Is there anyway I can get DMA working or will I have to wait for CentOS 5? Will any of the "unsupported" kernels work? (I would try Ubuntu's kernel on CentOS, as I am successfuly using that distribution, but it is a bit stupid not to use SELinux and it probably wouldn't work either).

You don't need a Red Hat subscription to get any SRPMs from RHEL. The GPL requires that they provide them for free.

Jim, I don't know if this discussion has been taken off-list, but why don't you just get this service (more specifically the Application Stack) from Redhat?

Alfred _______________________________________________ You don't need to reinstall the lated NVIDIA driver every time you update your kernel. In fact, this will cause problems if you need to revert back to your old kernel. You just need to install a new kernel module compiled for that version of your kernel. If you install the entire driver package, you will be installing new versions of all the related libraries, too. Then if you revert to the earlier kernel, that kernel module be an earlier version that doesn't match the version of the newer libraries, and you'll have a similar problem. Then to fix this one, you'll have to install the earlier kernel sources to recompile the kernel module for that kernel... And so on, and so on... If you know you'll never revert to the earlier kernel, it's okay to just install the whole new driver package. If you might revert, it's better to learn how to install just the kernel module. I forget the exact syntax, but if you do 'man nvidia-installer', all the details are there. Even better, HP supplies the nvidia drivers as RPMS. These RPMS are for RHEL, and include a script /etc/init.d/nvconfig. At startup, this script checks to make sure that the current kernel has an nvidia module. If it doesn't find one, it installs just the kernel module, no fuss no muss. The HP RPMS are just the nvidia drivers repackaged into RPM form. I recommend either using those RPMs, or at least extracting the /etc/init.d/nvconfig script from the RPM and be done with it. That's what I did.

IBM x305 slowdown?
by Chris Boyd 24 Oct '06

24 Oct '06

Hello: I have an odd problem with an IBM EServer XSeries 305 (aka x305). Sometimes it seems to just sit there, completely unresponsive to the command line (ssh and console), for several seconds. Other times it works normally. top will sometimes die with a floating point error while waiting for it to start. When top does work, it often shows a system load of 0.5, with high interrupt load. At first I though that the tg3 driver was not playing nicely, so I disabled the onboard NICs and installed a 3Com card. This seemed to clear up the problem, but it's now returned two days later. System is running CentOS 4.4, no X, Apache and MySQL. CPU is a P4 1.8GHz 512MB RAM 40GB ATA-100 disk Any suggestions on where to look next are appreciated. --Chris

python-interactive for CentOS/EL 4
by Will McDonald 24 Oct '06

24 Oct '06

Hi all, Could anyone point me in the right direction for a package that provides the 'interactive' module for Python? I need to do some SSH stuff in Python so I grabbed python-paramiko from RPMForge (as always, thanks Dag & co.). Paramiko appears to be dependent on python-crypto but the RPM doesn't require it.. [wmcdonald@willspc ssh]$ ./demo.py Traceback (most recent call last): File "./demo.py", line 33, in ? import paramiko File "/usr/lib/python2.3/site-packages/paramiko/__init__.py", line 69, in ? from transport import randpool, SecurityOptions, Transport File "/usr/lib/python2.3/site-packages/paramiko/transport.py", line 32, in ? from paramiko import util File "/usr/lib/python2.3/site-packages/paramiko/util.py", line 31, in ? from paramiko.common import * File "/usr/lib/python2.3/site-packages/paramiko/common.py", line 99, in ? from Crypto.Util.randpool import PersistentRandomPool, RandomPool ImportError: No module named Crypto.Util.randpool So I've grabbed python-crypto from RPMForge too and now I appear to need python-interactive or similar... [wmcdonald@willspc ssh]$ ./demo.py Traceback (most recent call last): File "./demo.py", line 34, in ? import interactive ImportError: No module named interactive The import causing the problem is... import paramiko import interactive And the code snippet where interactive is used is... chan = t.open_session() chan.get_pty() chan.invoke_shell() print '*** Here we go!' print interactive.interactive_shell(chan) chan.close() t.close() I've Googled a bit but "python", "module" and "interactive" generally return about a million results all relating to alternative interpreter/CLIs. This is all vanilla setup other than the RPMForge bits. [wmcdonald@willspc ssh]$ rpm -q python python-2.3.4-14.2 [wmcdonald@willspc ssh]$ rpm -q python-paramiko python-crypto python-paramiko-1.6.3-1.el4.rf python-crypto-2.0-1.2.el4.rf Will.

They store the backup database on a local drive, and if you should loose that db, you'll have to manually scan all your tapes before you can retrieve any data. Yes, you can manually backup the db somewhere else, but you can't easily put it on tape. Sure, you could simply dump the contents of each tape to another system with Arkeia's CLI, but in my case, it was 24 hours per AIT3 tape! Since this was in a library, I had 9 tapes to get through. The best backup arrangement I've used is rysnc to another system. I have it worked out in a very nice way to automate offsite storage to my colo. I never recommend Arkeia to anyone... Sorry to be such a stick-in-the-mud about it, but Arkeia let me down in a very severe manner, and I don't wish anyone else to suffer through the same problems I had. HTH Mark

$HOME variable not set from init script
by Oliver Schulze L. 23 Oct '06

23 Oct '06

Hi, I'm using Centos 4.4 with: mimedefang.org + spamassassin.org Mimedefang(MD) is a perl program that calls SpamAssassin(SA) perl module. The problem I'm getting is that from update 4.4, SA does not seems to find the $HOME variable only when it is called during system boot. If you later login as root and run: $ service mimedefang restart then SA does indeed find the $HOME variable I checked the /etc/init.d/mimedefang file and the chain of commands seems to be this: /etc/init.d/mimedefang -> daemon function from /etc/init.d/function -> /sbin/runuser SpamAssassin perl module is called from the mimedefang perl program. I'm thinking that /sbin/runuser is the root cause of the problem. My questions are: - does /sbin/runuser set the $HOME at boot time? - should /sbin/runuser be called with the -l option? Thanks Oliver -- Oliver Schulze L. Get my e-mail after a captcha test in: http://tinymailto.com/oliver

23 Oct '06

I have a Cyrus installation with postfix and openXchange. I get the mails from catchall account with procmail and distribute with the mail server. Now I have a new site office where couples of staff members are going to be relocated. Since we have only an ADSL line on site office if there any way I could forward the mails for these staff members to another Mail Server with dynamic IP address? Any input will be really appreciated. Thanks Rajeev R. Veedu.

ARC SERVE BACKUP.
by Rajeev R Veedu 23 Oct '06

23 Oct '06

Recently we have started using Arc serve backup. The Arc server and the tape library are connected to a Windows 2000 server machine and the data files are stored on many Samba file servers. I have Linux Client Agents installed on all Linux Machine. Now the problem is that when Arc Serve backup the file it always backup the full files irrespective of setting for a differential backup. I think the Arc serve is not able to set Archive bit on the file system. But it does for windows. Has any one in the list experienced this type of problem? Any advice or guidance would be really appreciated. Thanks Rajeev R. Veedu

You can follow the full story of my testing at CentOS Bug Tracker with 1419 id, http://bugs.centos.org/view.php?id=1419 Actually i'm running the stock kernel 42.0.3 in affected host with a lil more stability appreciated than previous kernels released but not really stable in certain situations (heavy i/o load on external usb 2.0 disk). [root@fattybox ~]# cat /etc/grub.conf | grep vmlinuz-`uname -r` kernel /vmlinuz-2.6.9-42.0.3.EL ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 [root@fattybox ~]# dmesg | grep ACPI ACPI: Unable to locate RSDP Kernel command line: ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 ACPI: Subsystem revision 20040816 ACPI: Interpreter disabled. What's sure, the system was running rock solid with 4.3 release and 22.0.2 kernel. From that point, any update to kernel or pkgs to 4.4 (34.x.x to 42.x.x) i get the same issue. The call trace (taken from 1419 id. at bug tracker and re-pasted here) is almost allways the same, and it happends normally when lot of i/o work is performed on an USB external disk, locally or via NFS/exported.

I know usb external disks are used with scsi emulation from the point of view of kernel and they are not a really good approach for massive data storing (rather using scsi units mainly/directly) but i have almost a TB on that disks... By the way i use the workaround of not writing concurrently to that disk for a long time or for long chunks... heh, no more clues unless i rescue the old 4.3 and 22.0.2 raw hd/image for that old host serving as NAS. Don't know if all of this will be helping, anyway... Good luck! Jose.
