Description of problem:
I have just upgraded to the latest development kernel and the computer
will not boot.  I get the following message:

Red Hat nash version 4.1.9 starting
insmod: error inserting '/lib/ext3.ko': -1 Unknown symbol in module
ERROR: /bin/insmod exited abnormally! 
    Reading all physical volumes. This may take a while
    Found volume group "root" using metadata type lvm2
    4 Logical volumes in volume group "root" now active
mount: error 19 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
Umount /initrd/dev failed: 2
kernel panic - not syncing: Attempted to kill init!

Version-Release number of selected component (if applicable):
kernel-2.6.8-1.541

How reproducible:
Always

Steps to Reproduce:
1.Boot kernel kernel-2.6.8-1.541
2. Kernel Panic
3.
    

Actual Results:  Machine fails to boot with kernel panic

Expected Results:  The macine should boot normally as it does with
other kernels (except kernel-2.6.8-1.538, which breaks in a different way)

Additional info:

The boot partition is ext3 on a primary partition, the rest of the
system is ext3 on LVM
