CentOS 5 Hardware :: R- Upgrading Kernel Only To Get Hardware Support
Oct 28, 2009
i have recently bought a system which has intel atom and my Lan card hasn't been installed on the system, i am using centos 5.2, i have read in some articles that Centos 5.4 directly support this LAN Card,so will upgrading the kernel for the Operating system help, or i have to download the whole iso for 5.4 and install it over the existing if upgrading the kernel will help which file i need to download to upgrade the kernel and where can i download that file.

I'm setting up a raid 5 on several hard disks with a layer of lvm on top for good measure.I know the recent kernels support growing software raid, but since centos runs 2.6.18, I wanted to make sure it'll work. Does the centos kernel support growing raid devices?

Does this mean kmod-xfs is no longer needed in centos 5.4 x64?

I have 2.6.18-164.2.1.e15 running on Hyper-v. I did yum update and noticed that kernel is upgraded to 2.6.18-164.9.1.e15. If I try to boot into the new kernel it hangs with message first "switchroot mount failed" and then "kernel panic". This is probably related to Hyper-v drivers installed in the old kernel. First question: Do you think this is correct? Is it possible to somehow disable Hyper-v drivers so I can boot into the new kernel and then reinstall drivers? There is nothing in Microsoft documentation about uninstalling Linux Integration Components.

I have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)

I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.

I have one machine where I have several versions installed on different partitions. The base partition (/dev/hda1) is Slack 12.1. On a spare partition (/dev/hdc4) I had installed Slackware64-current. Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot. I know that with the new kernels the hd* designation has been removed, and have already redone that fstab (accessing it from a different boot) to reflect the sd*. Here is the slack64 section of my lilo.conf:
Code:
# Linux bootable partition config begins
image = /other/spare4/boot/vmlinuz

I am currently running Kubuntu 9.1, quite happily (triple booting macbook with snow leopard and Windows 7). I would like to upgrade to Ubuntu 10.04, but I have a few questions first. Correct me if I am wrong, but Kubuntu is just Ubuntu with the K Desktop Environment, no? So if I were to wipe my partition and install Ubuntu 10.04, I could then install the K Desktop Environment and have Kubuntu 10.04? (sudo apt-get install)
I have been trying to find a way to "see" my kubuntu partition while booted into either mac osx or windows. My kubuntu is currently using the ext4 filesystem though, and there are no drivers to make this work... Is it possible to install Kubuntu onto a filesystem other than ext2/3/4? Ideally I would like to install it onto NTFS, but i know in previous distros (6.1, 7.1) this was not possible. FAT 32 would work for me too,as my partition is only 15gb. Or does anyone know of any drivers for ext4 for mac and windows?

We are currently running Redhat 5.4 64Bit (Build 2.6.18-164.e15) however having issues with tar files that are greater than 2TB in size.
We have been told that upgrading the kernel to support the ext4 file system (supported in version 5.5?) and mounting the current 10TB nas share as an ext 4 file system may solve our over 2TB file size issues. Are their limitations within the ext3 file system that cause issues to files greater than 2TB and if this is the case Do we have to update the kernel (complete rebuild), or can we load a package on the redhat box to support the ext 4 file system Where do we get the upgrade/package. I have logged onto the redhat site and can not find kernel updates but can find the full installation packages. We are not connected directly to the internet and do not have access to the update repository

When upgrading kernel via RPM, do I just need to download the RPM, and then do:
rpm -ivh file.rpm ?
Is kernel-headers needed?
Do I want to use force on either?
Example:
# wget ftp://ftp.pbone.net/mirror/ftp.cento...1.el5.i686.rpm
# rpm -ivh kernel-2.6.18-238.12.1.el5.i686.rpm

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

I've never compiled a kernel before and I'm in need of the 2.6.28 kernel (two words: macbook aluminium).
I guess my biggest question is, will this guide work well for F10? I would hate to get half-way through it just to find out that F10 does something different than F08 or F09. Is there anything that you experts can see right away that would possibly be disastrous? If things do come to worse, I can simply select the previous kernel at GRUB boot right?
Or will the Fedora team be releasing the update soon through the package manager? Is there a way I can activate the development version and only get the kernel update?

I upgraded, using package manager, to the latest kernel (2.6.35.10-72); I upgraded also kmod-nvidia and kmod-wl to the latest version, and the upgrade worked.After restarting the PC, though, it wouldn't boot Fedora: it stops at:"setting hostname for <my laptop's name>:[OK]"then it simply hangs there. It doesn't move, it doesn't boot, it doesn't ask for a login and it doesn't let me use command line.I can, however, boot and run Fedora fine if I select the previous kernel from the GRUB menu.Anybody can give me a hint to find the cause of the problem?

As seen in the screenshot, my update manager won't let me mark the proposed kernel updates for installation.I have heard that I would be able to mark them after a few days have passed ( I don't know the reason, though). Well, now it's been 3 weeks that I have them as "proposed updates" and I still can't mark them.I decided to run apt-get upgrade in the terminal and here is the output:
Code:
~$ sudo apt-get upgrade
Reading package lists... Done

Was upgrading to the newest kernel in RHEL5 from 2.6.18-164 to 2.6.18-164.10.1 but when I rebooted the machine it gave me these errors.
Unable to access resume device(/dev/VolGroup00/LogVol01)
mount: could not find filesystem /dev/root
setuproot: moving /dev failed: no such file or directory
setuproot: error mounting /proc no such file or directory
setuproot: error mounting /sys no such file or directory
switchroot: mount failed: no such file or directory
kenel panic - not syncing Attempted to kill init!
So I rebooted the machine and picked the old kernel to boot up (2.6.18-164) and everything came back up fine. I don't understand why it keeps failing when trying to boot to the new kernel. I am using the yum upgrade command, is there a different command I should be using?

Code:
1. Upgrade the kernel and kernel-modules packages normally.
That sounds simple except that day-to-day, I don't run a stock Slackware kernel. I compile and run my own and always have. As I look back on my history with Slackware, I don't think I've ever upgraded kernel packages once I got a system up and running. When there's been big changes (2.4 to 2.6, for example), I've done a full re-install.
Most recently when I made the jump to 64bit, I did a full install using the huge.s kernel and once everything worked, I downloaded the current source from kernel.org and was on my way. I haven't booted huge.s since that day.
I do, of course, know how to upgrade my own custom kernel, but I like having huge.s installed as a backup. If I upgrade gcc/glibc, compile a new custom kernel and update lilo.conf/fstab without upgrading huge.s, then I will be left with only one working kernel.
So, my question is: is it simply a matter of running upgradepkg on the 6 kernel packages (headers, modules, firmware, generic, huge and source)? or is there more to it than that..ie, what about the system maps and symlinks in /boot?

I have been using SLES 10 SP1 so far with about 6TB Raid system without problems.I have upgraded the OS to CentOS 5.3 i386 and I have noticed the kernel can not recognize raid system larger than 2TB.Is there any parameters that I have to set ? or the i386 distribution simply does not support larger raid, so I have to use x86_64 version, instead?

I am running a CentOS 5.5 system which does NOT support VT Technology, so I am unable to use Xen HV. I am very happy with OpenVZ other than the fact that it doesn't support Windows, only Linux.I'd like to have VMWare Server 2.x installed, but it appears that OpenVZ changes the Kernel to, in my case, 2.6.18-194.3.1.el5.028stab069.6. The default kernel on my system is 2.6.18-194.3.1.el5.i386.If I change grub to load 2.6.18-194.3.1.el5.i386, VMWare will work but OpenVZ will not. If I change grub to load 2.6.18-194.3.1.el5.028stab069.6, OpenVZ will work, but VMWare will not.If I try to run /usr/bin/vmware-config.pl while in the 2.6.18-194.3.1.el5.028stab069.6 kernel, I get an error of:
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)?Using compiler "/usr/bin/gcc". Use environment variable CC to override.
What is the location of the directory of C header files that match your running kernel?[/usr/ src/ linux/ include]I'm so lost as what to do now..is there anyway I can compile both of the kernels together somehow?

I have a hand-built kernel in Lenny. It's much smaller and faster than the stock kernel and doesn't need an initrd, but I am not sure how to upgrade it in a way that will be compatible with the new udev package. The recommended procedure is to upgrade the kernel and udev together and then reboot before doing the rest of the upgrade, but obviously I can't do that.
There seem to be two possible procedures I could follow:
1) Upgrade kernel sources and rebuild and install the kernel, then reboot and upgrade udev. But then the new kernel would be booting with the old udev and I don't know if that would work.
2) Upgrade, rebuild and install the kernel, then upgrade udev without rebooting, ignoring the warning messages. Finally reboot into the new kernel.

I am building a live-cd using live-helper on Karmic (9.10). The process executes fine and I am able to build a live cd of ~200MB in size with minimal and xfce. But things does not work if I try to upgrade the kernel with the one of them from [URL] site. Ubuntu kernel team publishes the kernel for testing and I would like to upgrade the kernel for testing. But when I upgrade the kernel from inside the live-helper's interactive shell, it upgrades fine and iso gets created. While booting, it loads the kernel and errors out with the following message:
Code:
(initramfs) mount: mounting aufs on /root failed: No such device.
aufs mount failed.
I am running initramfs after installing the new kernel (a .deb file) using dpkg.
What else should I need to do for getting this to work?

I have an Ubuntu 8.04 server running 2.6.24-23-server. I have a godaddy account and I am trying to upgrade my os version to 10.04, which requires a kernel upgrade. I have tried ksplice but kernel 2.6.24-23-server is not supported. I have heard about screen sessions but I have not found it possible to reboot one screen while having the other screen stay persistent if it is possible.So the main question is how to update Ubunut 8.04 to Ubuntu 10.04 with out rebooting the entire server? Rebooting is completely not an option at the moment.

I upgraded my Ubuntu 11.04 laptop to kernel 3.0.1 and when I try to start Conky using my custom conkyrc, the conky process dies. I played around with it and discovered (through trial and error testing) that the code for the CPU temperature crashes conky. It worked before the upgrade. how I can get the CPU temp monitoring working again in kernel 3.0.1? Here is the code that is crashing conky:
