Description of problem: I updated a lot of stuff and kernel 541 and 541smp as well When I rebooted (541smp), the following appeared on screen ... ... Switching to new root switchroot - mount failed: 22 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! I then tried 541 plain with the same results. Then went back to 538smp eth0 still inactive on boot completion, but /etc/sysconfig/network-scripts/ifup eth0 will bring it up. During the 538smp boot, I noticed kudzu complaining - this is probably fixed in 541 ... Version-Release number of selected component (if applicable): kernel ... 541smp and 541 plain How reproducible: Both times I tried (once each). Needed to power cycle to recover. (But it did recover - to an earlier kernel Steps to Reproduce: 1. boot (as above) 2. 3. Actual results: Kernel panic Expected results: successful boot Additional info: Logs? do you need any logs?
This is my boot log - not so much has been captured.

What happens if you downgrade gawk to something other than 3.1.4 and rebuild your initrd?
Wow - I'm up with 541smp [user1@hoho2 ~]$ cat /proc/version Linux version 2.6.8-1.541smp (bhcompile.redhat.com) (gcc version 3.4.1 20040831 (Red Hat 3.4.1-10)) #1 SMP Wed Sep 1 18:15:33 EDT 2004 [user1@hoho2 ~]$ ---- I did a couple of things, ending up with remaking initrd as Bill suggested. The first thing I did was remember that I had previously moved /etc/modprobe.conf out of the way. I checked to see if there was a new version (came in the latest yum upgrade ??). Nope, so I moved the previously moved aside version back in. Then I tried to boot 541smp It still kernel paniced. I wrote down a few more lines from the console: loading ext3.ko module Creatng root device mkrootdev: label /1 not found Mounting root flesystem mount: error 2 mounting ext3 mount: error 2 mounting none Switching to new root --- then more or less (did not copy down) the lines given in the beginning of this bug report. == Then I booted back into 538smp and took a look at the mkinitrd The version of gawk was 3.1.4-1 - did not look for a lower version, but thought I would practice mkinitrd step. If I got the same initrd file as currently, then I would look for a different version of gawk. I first moved the old /boot/initrd out of the way (extension brok) Then built a new initrd: /sbin/mkinitrd /boot/initrd-2.6.8-1.541smp.img 2.6.8-1.541smp === Note that listing below shows my new initrd much bigger than the broken version (3rd line in listing). So, if it was different, why not try to boot it - and the rest is history.

As mentioned previously Works for me.
