Red Hat Bugzilla – Bug 220269
upgraded kernel panics
Last modified: 2007-11-30 17:11:51 EST
Description of problem:
Eversince I upgraded the kernel on my system after 2.6.17-1.2187_FC5, the system
cannot boot with the new kernel. I am attaching the photo I took of my screen
after trying to reboot with the newest kernel, 2.6.18-1.2257.fc5. It is also at
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. make sure grub will boot kernel-2.6.18-1.2257.fc5
Kernel panics, and so the computer cannot boot.
The system is an AMD x86_64. The hardware has not changed in more than a year.

I have a similar system at home, and there there is no problem running the newer
kernels. The output of lshal for my homebox is at
As you see, on the homebox I am running kernel 2.6.18-1.2239.fc5 which is not
yet the latest, but my office computer panicked with this 2.6.18-1.2239.fc5

It has been a month since I posted this severe problem, and I do not see any
reaction. I am just sending this in case people at RH/FC just forgot about it.
Can you remove "rhgb quiet" from the bootup parameters? That gives a lot more
To do that, hit 'space' when GRUB shows up, hit 'e' on the kernel, scroll down
to kernel .. line, and hit 'e' again. Remove the rhgb and quite. Hit Enter and

This is a MOV file taken with my digital camera.
Thx for looking into this. If there is a better way to capture the bootscreen,
let me know. Uploading a 16M MOV file does not look very efficient.
Here is a fix to the problem:
mkinitrd -v -f --preload=raid456 /boot/initrd-2.6.18-1.2257.fc5.img
The change I noticed after kernel-2.6.17-1.2187_FC5 is that the raid5.ko module
did not exist anymore, but only the raid456.ko module. Since my root partition
is on a raid5 array, the bug bit me.
Of course, I do not want to recompile initrd after every kernel upgrade, so
please either use the --preload=raid456 option at RH or let me know of another
hopefully permanent fix.
I just installed the latest kernel
and the bug is still there. So this thing does not bite anybody else with raid5?
How are the kernels for FC6?
I do not dare to upgrade to FC6 because of the bug. Will I be able to boot into
runlevel 1, and run the initrd fix?
