Hopefully someone more knowledgeable can answer your question about the USB driver. Do you have any Diagnostics for that USB drive that you can run on it? If not, see if you can download diagnostics from the web site of the manufacturer. Maybe a problem at 33554424 also?

Time delaying (or time lagging)
by happymaster23 08 Sep '08

08 Sep '08

Hello everyone, I have problem with time delaying on my CentOS powered server. I have tried to set time in BIOS and in OS (with saving time to BIOS), but time still delaying, so after month is about five minutes delayed. In past I was using this box with Windows and there wasn´t this time problem, but I cant warrant, that there are no hardware issues. So I was decided, that easiest way to fix this problem will be setting up the NTP. I have found many howtos, but I don´t believe them. So my question is: How to clearly set NTP in CentOS 5? Thanky you very much

Troubles with NetworkManager
by ABBAS KHAN 07 Sep '08

07 Sep '08

NetworkManager used to work fine for me but during the last few installations its a big hurdle in the wireless connectivity. I'm using Madwifi and its interface is correctly listed and working but I cannot connect to any wifi AP without NetworkManager. I've two interfaces: eth0 and wifi0. Starting NetworkManager doesn't show any notification icon in the top right in gnome and I believe its only activating the ath0 instead of wireless interface wifi0 but still I am unable to see any of the notification icon in the gnome as I was used to in past for any of the NICs. The error which I recieve upon logging into the gnome is: "The NetworkManager applet could not find some required resources. It cannot conitnue". But still, there are no errors in the syslogs besides the below ones particularly *"localhost NetworkManager: <WARNING> nm_device_802_11_wireless_scan (): could not trigger wireless scan on device ath0: Network is down*". Thanks in advance for the helpout.

xulrunner-devel package missing many header files
by hce 07 Sep '08

07 Sep '08

Hi, I've just installed xulrunner-devel from yum, but there are following header files cannot be found in xulrunner-sdk-1.9/sdk/include: mozilla-config.h mozilla-config32.h prtypes.h The include/xulrunner-sdk-1.9 constains those above header files, I did link to them, but xulrunner-sdk-1.9/system_wrappers/prtypes.h has a problem as well: #pragma GCC system_header #pragma GCC visibility push(default) #include_next <prtypes.h> #pragma GCC visibility pop At final, I could not compile VLC plugin with the xulrunner-sdk-1.9/sdk. Please advice how to fix it and where could I install a proper sdk? Thank you. Kind regards, Jim

Kernel panic installing CentOS 5.2 in Parallels on iMac
by Bart Schaefer 06 Sep '08

06 Sep '08

I'm unable to get much past the "boot:" prompt in the installer. The panic appears to be in powernowk8_init which according to http://rhn.redhat.com/errata/RHSA-2008-0612.html has a recently-fixed null-pointer dereference. That errata is from August 4; the latest CentOS install ISOs are from June. I tried the agp=off suggestion from e.g. http://www.centos.org/modules/newbb/viewtopic.php?topic_id=13512 with no success. Is there a good way to proceed here? Will there be new install media with the more recent kernel?

OT: Home NAS device
by Joseph L. Casale 06 Sep '08

06 Sep '08

I am looking for something that I can hack away like a NSLU2 but that thing only has one disc and worst of all its 100m interface. Anyone know of a device you can load Linux on that has maybe 2 discs like a NAS200 with a gig nic? I need a quiet device to act as a tftp-dhcp/web/dns system. I thought of just building one from a new Soekris board, or even a mini itx but hope there was something simpler/cheaper. Thanks for any reco's! jlc

Remove old kernel

The university department I work with recently bought some Opteron machines (two-processor 2350) HPs, and also has some recent Xeon (two-processor 5405) Dells. I ran a test on them with a Java parsing (natural language) program and found that the Xeons did 33.72 words per second, while the Opterons lagged at 20.04 words per second. These are both running the same Ubuntu version. It may not be a common or representative benchmark, but it is the kind of thing I'll be using my new machine for.
