Description Frode Tennebø 2005-12-16 06:49:22 EST
Description of problem:

At relatively frequent 
intervals (app. every 
two weeks) the OS hangs 
and I'm forced to do a 
hardware reset.

Just prior to the 
incident I have in /var/
log/messages one or two 
of those:

kernel: Trying to fix it 
up, but a reboot is 
needed


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

It has been like this 
for all FC4 kernels I 
have tried. This 
includes:

kernel-2.6.11-1.1369_FC4
kernel-2.6.12-1.1398_FC4
kernel-2.6.12-1.1447_FC4
kernel-2.6.13-1.1526_FC4
kernel-2.6.13-1.1532_FC4
kernel-2.6.14-1.1637_FC4

Currently I'm running 
(for a few hours):

kernel-2.6.14-1.1644_FC4

...but will shortly boot 
into:

kernel-2.6.14-1.1653_FC4

I will confirm when/if 
it happens again with 
any of these releases.

How reproducible:

It's periodically and I 
have no deterministic 
way of reproducing it.


Steps to Reproduce:

Additional info:

Prior to the actual hang 
I have the following in
