Description of problem:
When I restart the networking on a couple of our machines (Dual EM64T Xeon 3.6Ghz, 4 Broadcom NICs (2 onboard, 2 cards, 2 bonded pairs), IBM x346), the kernel panics and the machine dies.

Version-Release number of selected component (if applicable):
2.6.10-1.770_FC3smp

How reproducible:
Sometimes

Steps to Reproduce:
1. Restart networking (service network stop ; service network start)
2. Look at local console, see panic output

Actual Results:  The kernel panicked with the following output (manually copied from the console):

Kernel panic - not syncing: Aiee, killing interrupt handler!

Expected Results:  The networking should have stopped and come back up without the kernel panicking.

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

Thank you.

This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
