Description of problem:
I upgraded three machines kernels this morning.  One running fc2 to
the new kernel.  During it's reboot it locked up with a kernel panic.
This resulted in damage in my harddrive.  Lost /usr on my mail server.
 Before that I had already updated the kernel on my notebook(i686). 
During it's first reboot into the new kernel it locked up while
checking the root filesystem (ext3).  I rebooted with no problems at
that point and my notebook started up without issue.  Then this
afternoon after getting the mail server rebuilt, I decided to change
/etc/inittab to disable graphical boot on my notebook.  So, to test it
i rebooted my notebook.  Now i have the same kernel panic on my
notebook screen as I had on my mail server this morning.

Remounting root filesystem in read-write mode: [ OK ]
Kernel panic - not syncing: kernel/module.c:2043:
spin_lock(kernel/module.c:c0347240) already locked by kernel/module.c/2043

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

How reproducible:

Steps to Reproduce:
1. reboot

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

yes, upgrading to the newer kernel did indeed fix the problems I was having
