CentOS 5 :: Yum Kernel Update - Unable To Boot
Oct 24, 2010
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.

I have recently run an update and now we are unable to boot the newer kernel. We get stuck as below;
Memory for crash kernel (0x0 to 0x0) notwithin permissible range
Red Hat nash version 5.1.19.6 starting
Unable to access resume device (/dev/VolGroup00/LogVol06)
[Code]...
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?

After running update last night from 2.6.35.9-64 to 2.6.35.10-68 my laptop fails to start. Boot process goes most of the way to startup and then hangs just before login screen. Not sure what else to give as far as info.

This morning, I booted into my administrator account and checked for updates. There were a number (bogofilter, for one) but also a update to the 2.6.32-24 kernel. I installed the updates and rebooted the system. When I rebooted, the thought occurred to me (from reading another thread) that one of the reasons my Zareason desktop boots slower than my laptop (55 seconds vs 35) was that I have an external floppy drive attached, and perhaps the delay was a difference in my system checking for a bootable floppy.
So I went into the BIOS when it was booting to check to see if the floppy was enabled (it wasn't). Then I selected "Exit without saving" and resumed booting. What happened next was instead of seeing the Ubuntu icon and the six dots, I see "Ubuntu 10.04" and four dots. Then I get on the black screen these errors (sorry for any mistyping, I wrote them down on a sheet of paper as I had no other computer available to troubleshoot):
udevadm trigger is not permitted while udev is unconfigured
udevadm settle is not permitted while udev is unconfigured
udevadm settle is not permitted while udev is unconfigured
udevadm settle is not permitted while udev is unconfigured
ALERT! /dev/disk/by-uiid/939af864-c1a8-41d7-9b24-91d25685b6 does not exist. Dropping to shell
Busybox v1.13.3 (Ubuntu 1:1.13:3-1ubuntu11 built-in shell (ash).
Enter 'help' for built-in commands
initramfs
Googling around once I got into work and had computer access, it seems that the problem is GRUB has lost track of what partition I should boot from? Here is a thread which might be relevant: [URL]. Before I left for work, I went into the BIOS again and looked at the CMOS settings--everything looked normal. I once again exited without saving anything. I was going to try selecting an earlier kernel from the GRUB menu on boot, but couldn't remember the key to press.
I found out later today, to enter GRUB 2 it's been changed to the shift key, and not the F2 key like it used to be. One poster on the aforementioned thread said his system would boot ok to the earlier kernel. The thread above has as its solution to either try to tell GRUB where your boot partition is and/or re-installing GRUB. I have /home on a separate partition, so if I need to do a re-install I can do so without it being a major pain. Sda1 is the partition which has the OS.

I am unable to boot my Fedora 14 after last nights kernel update. When I start the boot up and hit F2 the system fails after outputting the line : Starting vservers of type 'default'. At some point the console displays an error message :
serial8250 : Too much work for irq17
How do I restore my previous version? I know some people have suggested in the past - just modify the grub.conf but how? When I boot off the cd I only get access to the liveuser disk. I need to have access to my own /boot/grub/grub.conf file.

after update to kernel-2.6.18-164.el5 one of the 2 NIC's of my machine are only found at 1 of 4 reboots. Using the old one kernel-2.6.18-128.7.1.el5 all is fine. This are the to NIC's:
00:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
00:0b.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 0c)
And the Intel one, makes the problems with the new kernel.

The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
# cat /etc/grub.conf
default=0
timeout=20

I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

I am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
[code]....
I can't see anything wrong and I did not change/try anything.

I try to update my kernel to 2.6.18.128.4.1.el5 using
# yum update
After # yum update # rpm -qa kernel*|sort gives the following:
kernel-2.6.18-128.1.14.el5
kernel-2.6.18-128.1.16.el5.centos.plus
kernel-2.6.18-128.4.1.el5.centos.plus
kernel-2.6.18-92.1.18.el5
kernel-2.6.18-92.el5
kernel-devel-2.6.18-128.1.14.el5 .....
This my grub.conf:
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=5.....
yum update installed:
CentOS (2.6.18-128.4.1.el5.centos.plusxen) and
CentOS (2.6.18-128.4.1.el5.centos.plus)
both are not working. I have to run the system using: 2.6.18-128.1.14.el5. Upon trying again #yum update it says that no packages are marked for update. Can I manually install the desired kernel? Do you know a reason why yum update is not automatically installing the proper kernel?

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 installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors:
[root@vm01 ~]# grub-install /dev/sda
/dev/sda: Not found or not a block device.
[root@vm01 ~]# grub-install /dev/sde
/dev/sda1 does not have any corresponding BIOS drive.
[root@vm01 ~]# grub-install /dev/xvda
/dev/xvda: Not found or not a block device.

I am currently working to get to a stable dual boot Win7/CentOS 5.5 configuration on a Dell Latitude E6510 with the Intel 82577LM chipset. I haven't gotten the Centrino N WiFI chipset working yet, but the Eth0 device was working just fine.However, yesterday I did a system update. I did not pay close attention, but I believe the update did mention networking, because I thought it might help me get my wireless going. Now, Eth0 fails with the message, "Determining IP information for eth0... failed; no link present. Check cable?" It does this at boot up and if we try reactivating it once the system is up. We have tried unstalling and re-installing the driver.The Window 7 boot sees the adapter and runs just fine. I was at a different site location yesterday when everything was working, but my co-workers and I can't help but think it might be related to the update yesterday, since everything worked prior to the update and Windoze 7 works fine with the adapter.
I have not been able to mount my NTFS harddrive on the CentOS side, despite installing fuse, and I don't have wireless, which makes it difficult to get access to new drivers. I also have a FAT32 partition that would be great to share between the boots for passing info, but I haven't found a way to mount a FAT32 partition in CentOS.

Last I upgraded one of our cent 5 boxes which is running kvm with a mix of centos and windows VMs.After the update performance just tanked on the XP guest, but the others (including other windows VMs) are just fine.I checked with our good friend google and didn't really get any help there.We're hoping to NOT have to rebuild the XP guest, so I thought I'd check in here first.
This is CentOS release 5.5 (Final) with kernel

I have used Ubuntu since 8.04 LTS on my IBM T30 and A31 for almost three years now but recently all of them have problems with kernel updates(? maybe I am wrong but it was very clear that they failed after a kernel update). I have tried all three solutions provided by [URL] but none worked for me. My last A31 failed to boot yesterday after some updates (I noticed that there was a kernel update). It has 10.04 LTS on sda5. Dual boot (Windows XP on sda1 but rarely use it). Now it can't load kernel. What shows on the screen is:
GNU GRUB version 1.98-1ubuntu7 Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. On the other T30 I had the same problem. I installed Windows XP and clean installed Linux Mint 8 and so far it is working alright. But on this machine I have an unfinished project that I really want to save it.

I just updated my kernel to kernel-2.6.29.5-191.fc11.x86_64 on my x64 system, after I reboot my machine, the Fedora loading bar comes up and finishes but then no gui comes up. I attempt to issue commands at the hanging prompt that comes up but nothing happens. I can boot into my older kernel just fine but not the updated one.
What can I do?
