Description Per Steinar Iversen 2003-06-30 08:13:53 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030505

Description of problem:
When disconnecting and then reconnecting an ieee1394 device the kernel hangs on
smp systems. This does not happen when using a uniprocessor kernel, the problem
is thus likely due to the ieee1394 driver not being smp safe.

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

How reproducible:

Steps to Reproduce:
1. Connect ieee1394 disk
2. Disconnect ieee1394 disk

Actual Results:  Kernel hangs, no response, not even SysRq works.

Expected Results:  Nothing much, at most a message about disconnecting the
ieee1394 device.

Additional info:

The problem does not occur when running a uniprocessor kernel.
The hardware is a 2 CPU Dell 2650, 2GB RAM.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
