I am trying to install CentOS 5.3 on a computer where I successfully installed Windows XP.
Booting from the DVD I got the following error:

Here's the text from the serial console before I rebooted:

My root server is using CentOS release 5.2 (Final), kernel 2.6.26.5-rootserver-20080917a, SMP, 64-bit This Oops happened yesterday and before that it happened on March 14th of this year, and before that on January 31st of this year, so a repeating pattern. On the January 31st Oops, I just rebooted. On the March 14th Oops, I reformatted the two swap partitions as follows: mkswap -c /dev/sda2; mkswap -c /dev/sdb2 On this last Oops, I turned off the swap for 24-hours, then decided to turn it on again after doing the above mkswap again. During the previous uptime, I had dumpcap packet capture running, but this last reboot, I'm not going to run it.
Does anyone have any idea what this is? I'm running F14 kernel 11-83, everything else is rock solid but I get this crash randomly, sometimes it runs for days no problem other times it crashes within a few hours.Someone recommended I run memtest86, I did for 24 hours and it showed no problems.

I've been trying to install Opensuse 11.3 from the Kde live cd, but the installation hangs when I'm almost done. Right at the beginning the installation is interrupted right with text that among other things says:
Bug: unable to handle kernel paging request at ffffc90010b8000. After a while though, the installation picks up and continues by itself. I'm then able to complete the necessary steps and I reboot the system so that it can complete the installation.
After reboot there is a new text message that says that the bios does not support EEC memory or something to that effect and then continues with the installation. When it has completed 82% of the autoconfiguration the installation just stops and stays that way.
I've had no problem installing previous releases, from 10.2 up to 11.2, on the same machine.
I've checked md5 sum and also checked the media before proceeding with the installation.
Upon reboot after the first installation step, I also tried the failsafe mode but got the same result.
all of the following are made through live usb creator. when i tried with F11 i686 live kde, I got the following error: Bug: unable to handle kernel when i tried with F11 x86_64 live kde then at the time of installation my screen got blurred.

What's the centos-approved way to handle group environment configuration? Let's say there are users in, oh, 4 different groups. Let's use the usual suspects:
accounting
warehouse
admin
netadmin
and I want to set up environment variables and maybe some pathing that are specific to a given group. So that when 'joeblow', who is a member of group 'warehouse', logs in, the pathing and environment variables (and whatever else) that is needed for users in the 'warehouse' group is set up and configured.
What I was initially looking for was an /etc/groups.d, and in /etc/groups.d is
/etc/groups.d
accounting.sh
warehouse.sh
admin.sh
netadmin.sh
As part of the login process, the group memberships for the login username would be examined, and for each hit the respective /etc/groups.d/ script would be run. I'm not seeing anything like that, so I'm assuming centos uses some other mechanism, but I'm obviously not using the proper keyword mojo. Can someone point me to where this mechanism is described?
I am running an old kernel for my XEN VPS CENTOS 5.5 x86_64 - 2.6.18-164.el5xenI did a 'yum update kernel' but when I rebooted still the same. I have downloaded the version 'kernel-2.6.18-194.32.1.el5' I cannot find grub.conf in both etc and boot, yes grub is installed via yum.

I had a Centos 5.5 system working great...and then due to crazy curiosity, installed the kernel update. Did this through the graphical interface, uncheck all update other than kernel. It downloaded, installed fine..After reboot now all I get is GRUB_ and then nothing else! I waited 3-4 minutes and had to shut down system. Have been googling around but thought I will post it here as well..When I boot with Win7 and use Ext2fsd to check, the boot folder is empty. Not sure if this is because ext2fsd does not read boot folder or it got wiped out by the yum upgrade process.

The kernel version we were at was 2.6.18-194.el5 and the update move us to 2.6.18-194.17.1.el5. I've done some googleing but I'm unable to work out exactly what I need to do. I'm guessing the new kernal is missing a module?
I need to understand southbridge related code in linux source code.
For that I have downloaded Linux source code version:2.6.28 .

Is Linux source code contains southbridge specific code?If so where can I find the code?
A FC10 server hung and had to be power-cycled. I suspect it hung because of an nfs mount timeout.
Now it does not boot. The error is libc.so.6 not found. Kernel panic. Attempting to kill init.
Booting under rescue:
ls: cannot access libc-2.8.so: Stale NFS file handle
Is there a way to reboot to a clean state? There must be some NFS cache file.
I also tried to cp rescueCD:/lib64/libc-2.8.so to the old lib64 dir, but get the same "Stale NFS file handle" message.

djmack-5/19/2011-I have purchased an ASUS K52J (intel i7) laptop. I have installed Centos 5.5 (64 bit) from CDs. The I got all the updates and it's now up to 5.6. I have two problems.
(problem-1) - Using the GUI (System->Administration->Hardware) I can get to a Device Manager screen. It shows a JMC250 PCI Express Gigabit Ethernet Controller. Using the GUI (System->Administration->Network) I can only see the wireless (wlan0) as configured and active. The ethernet card is not seen as ether 0. I've seen there are downloads to solve this problem, however I've been 100% unable to do and or understand them. I don't know how to build the kernel and I don't have any source code. I only have the binaries (I think). Is there a version of the kernel that I can put on CDs that has understanding of the ether card I referenced above?
P.S. I've downloaded a binary fix and it says it needs 20 or so dependencies (I have zero idea how to get those).
P.S. I've downloaded a source fix and I couldn't get it to install (I'm not a linux kernel build knowlegable person). I don't have the source either.
(problem-2):As stated above I need direct (RJ45) access to the laptop. I currently have the wireless card working but I have no idea how to get this to work with httpd, ssh, scp.I can access things via a web browser right on the laptop. I cannot access this laptop via a web browser from any other box. I cannot access this box via ssh or scp.I disabled the firewall and I disabled the SELinux security.I am stumped as to why I cannot see this ASUS laptop via httpd and/or ssh/scp.I can ssh and scp to other linux servers but these servers cannot ssh or scp into this laptop.
I got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.

View 2 Replies View RelatedI just set up a new CentOS 5.5 system (using the 5.5 DVD, yum updated all packages to latest) which unfortunately due to various issues and most critically availability, has an ATI-4350. The install went OK but X does not detect the card properly so it's using the slow VESA driver. I followed the instructions here [URL] to download and install the ATI driver. It appeared to be correctly installed but not used.
Display still detects my monitor and 4350 as unknown and using some "Vendor supplied driver". Yet under the "Dual Head" tab, if I would to enable it, the ATI-4350 comes up as an option, hence implying that the driver was corrected installed and the card is actually detected. I suspect it might have to do with my Xorg.conf, although trying to edit in several ways didn't make it work.
