More on Linux on the OQO
by Robert Moskowitz 24 Sep '08

24 Sep '08

I am going over: ftp://ftp.oqo.com/unsupported/linux/OQOLinux.html This is for the 'older' model 1, I have the model 2. The files are 18 mo old, and relate to kernel 2.6.10. Of course I want to avoid a custom kernel, but please help me understand what is being covered here: "2. Enable crusoe processor in kernel .config CONFIG_MCRUSOE=y" What is the crusoe processor? 3. Programs such as 'hwclock' synchronize on the RTC periodic interrupt for accuracy. We need to disable RTC IRQ support in the kernel as we don't get the periodic interrupt. In the kernel .config set CONFIG_HPET_RTC_IRQ to 'y'. This enables the high performance event timer irq and in the process disables the rtc driver interrupt code: CONFIG_HPET_RTC_IRQ=y" How do I do this with the Centos kernel? "4. ACPI processor module (idle handler) interferes with transmeta longrun scaling. Set ACPI_PROCESSOR to 'n' or not set # CONFIG_ACPI_PROCESSOR is not set" Does this mean I have acpi=none in the kernel line? I really hope not. "5. Kernel preempting option currently causes a bug to show up in the wifi drivers, turn it off CONFIG_PREEMPT=n" I would hope to be using the dkms madwifi stuff. Do I need this? "6. Download the latest rtl8150 drivers from CVS at: https://sourceforge.net/cvs/?group_id=15970. The drivers in the base 2.6.10 tree will kernel panic upon removal of the dock. Copy the new driver to linux/drivers/usb/net/rtl8150.c" Don't see this as a problem as Centos has rtl8150 support. "7. In drivers/input/serio/i8042-io.h, add 'i8042_noloop = 1' in the function i8042_platform_init(). You only really need to do this if you have OQO subprocessor version 10/5 (It'll say 'EC Build 10/5' on BIOS post)." What is this all about? Still haven't actually tried an install.....

install of Pod::Simple through CPAN
by Al Sparks 23 Sep '08

23 Sep '08

I'm running CentOS 4.4. I'm trying to install swatch (a log watcher) using CPAN. It's getting hung up on trying to install a dependency, Pod::Simple So before I get too wrapped up in this, I have the following questions: 1. Is there an alternative way to install swatch? I didn't get a hit when I tried yum. 2. I'm not wedded to swatch. Is there another log checker out there that will work with CentOS? 3. Lastly, here's the error I get when I attempt to install Pod::Simple through CPAN: Test Summary Report ------------------- t/xhtml01 (Wstat: 512 Tests: 26 Failed: 2) Failed tests: 24, 26 Non-zero exit status: 2 Files=53, Tests=1095, 9 wallclock secs ( 1.30 usr 0.10 sys + 7.22 cusr 0.78 csys = 9.40 CPU) Result: FAIL Failed 1/53 test programs. 2/1095 subtests failed. make: *** [test_dynamic] Error 255 ARANDAL/Pod-Simple-3.07.tar.gz /usr/bin/make test -- NOT OK //hint// to see the cpan-testers results for installing this module, try: reports ARANDAL/Pod-Simple-3.07.tar.gz Running make install make test had returned bad status, won't install without force Failed during this command: ARANDAL/Pod-Simple-3.07.tar.gz : make_test NO

ASUS P5GC-MX/1333+ WD SATA
by Eduardo Grosclaude 23 Sep '08

23 Sep '08

Hi, I'm puzzled by an ASUS P5GC-MX/1333 with a WD320AAJS disk. My 5.2 DVD refused to see the hard disk. As the CD happened to have a bad MD5 sum, I assumed this was due to a bad burnt image. Backed off to 5.1. Installation of 5.1 to /dev/sda went OK, then I upgraded by yum to 5.2. But, at the next boot, the new kernel can't see the disk. Only when BIOS IDE Setup is "compatible" I can boot the new kernel. However, the disk shows up as /dev/hdc and performance is noticeably slow. If I choose any other mode, nash complains that any LVM groups can't be found and panics away. I/O in general is terrible. Copying a CDROM to a file with dd renders the machine nearly unusable. The kernel provided in 5.1 can work in the BIOS IDE Setup "enhanced/SATA" and performance is really good. Hdparm when under the current kernel says 3.51 MB/s buffered speed, whereas for the older kernel it claims some 111+ MB/s. I have updated the BIOS ROM to no avail. What am I missing? Is there anything I can do except keep trying kernel updates? TIA -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

Centos Kernel 4.7 Compile Help
by Steve Moccio 23 Sep '08

23 Sep '08

Hello Everyone, I wanted to recompile the kernel from source. I downloaded the source rpm (kernel-2.6.9-78.0.1.EL.src.rpm) from centos and installed the rpm. In /usr/src/redhat I unzipped and untard the linuxx-2.6.9 base files. After doing that I wanted to patch the kernel with the numerous patch files that came with the src rpm. The problem that I am having is that a lot of the patch files fail an example: patch -p1 < ../linux-2.6.9-megaraid-update.patch patching file drivers/scsi/megaraid/mega_common.h Hunk #1 FAILED at 27. 1 out of 1 hunk FAILED -- saving rejects to file drivers/scsi/megaraid/mega_common.h.rej patching file drivers/scsi/megaraid/megaraid_mbox.c Hunk #1 FAILED at 10. Hunk #2 FAILED at 217. Hunk #3 FAILED at 244. Hunk #4 FAILED at 286. Hunk #5 FAILED at 340. Is this not the right procedure for patching the kernel? Any insight would be appreciated. Thanks, Steve

Need uuid rpm for CentOS-5.2
by James B. Byrne 23 Sep '08

23 Sep '08

On my development system I have installed PostgreSQL 8.x from the yum.pgsqlrpms.org repository. I am getting a dependency error: Error: Missing Dependency: libossp-uuid.so.15 is needed by package postgresql-contrib I can find references to this file in an rpm for fc7 (uuid-1.5.1-3.fc7.i386) but nothing else. Is there a place that I can obtain a CentOS version of this package? Failing that, is installing uuid-1.5.1-3.fc7.i386 on CentOS-5.2 an option?

OQO mod2 arrival
by Robert Moskowitz 23 Sep '08

23 Sep '08

My OQO mod2s just arrived! All 4 of them; portable testbed here it comes!!! I hope.... The units weigh in at ~.75lbs, and measure aprox. 5 5/8 x 3 3/8 x 1 1/8" A little larger when you push up the 5" screen to reveal the keyboard. WiFi, Bluetooth, HDMI, and a single USB built in; an adapter for VGA and Ethernet. (WiMax extra, I think the touch screen is also optional and I did not get that). The processor is a VIA C7-M 1.5Ghz processor, with 1Gb memory, and a 60Gb harddrive. XP pro installed. From XP tools, I have learned that: WiFi is - Atheros AR5006X5 Ethernet is - Realtek RTL8139 Video is - VIA/S3G UniChrome ProII IGP Audio is - SigmaTel Default screen res is 800x640 (can increase then use capacitor scroll bars). I have not looked to see if I can get into the BIOS, I expect to be able to boot from a USB CDdrive (it comes with a recovery CD). There are instructions on the net for installing UBUNTU (http://en.wikipedia.org/wiki/OQO) but of course I want Centos on it. Should I be expect any supprises given what I have learned so far? Minimally, these will be test units so only basic Gnome functionality and of course server stuff (wired, wireless, bluetooth) need to work. Would be nice to make one my traveling notebook as well.

RAID / OS Monitoring tools ?
by kevin kempter 23 Sep '08

23 Sep '08

Hi List; I just got a new server (my first **real** server). It's a dell 2900 : quad core XEON (with a spare slot for a 2nd quad core chip) 8G memory (expandable to 64G) 8 hot swap SATA HD slots onboard PERC6i RAID controller etc I initially setup the system / RAID as follows: 1) booted off the dell setup CD 2) walked through the RAID setup and formatted the drives 3) the setup bombed when it asked for a RHEL install media (I suspect cause I gave it a CentOS 5 install DVD instead) 4) powered off 5) restarted the box with the CentOS DVD in the drive and installed CentOS 5 The RAID configuration was as I had set it up in the DELL setup cd so I'm happy. Now I want to be able to monitor the box, specifically with respect to the RAID drives so I'll know if one has gone bad and the RAID configuration has failed over to it. Anyone have any suggestions for tools to use ? Thanks in advance...

You shouldn't need to do anything that fancy just to find out if something fails. -- Bowie

database diff's?
by Gabriel Norton 23 Sep '08

23 Sep '08

Hi, I'm trying to figure out what bits of info I need to ad to a DB to manualy add users to an app (eGW) and was wondering if anyone had a better way to find the differances in two states (pre/post change) of a database. Only thing I could come up with was to do a DB dump to a file before and after then run diff on them. Anyone have a slicker, better, faster, not a as gee-wiz there should be a better way to do this. Thanks, Gabe
