Oops on linux 2.4.20-ac1

[Orion Poplawski <orion@cora.nwra.com>]

I've been having a number of issues, mostly system lockups, with a 
machine of ours - a dual proc athlon.  I've removed some hardware and I 
haven't seen a hand recently.  However, we got an Oops message recently. 
 I lost that message because it wasn't written to any log (any way I can 
fix that?).  So, I upgraded the kernel to 2.4.20-ac1.  Under that I 
started getting Oops quite frequently.  Here is my first attemp at 
processing the message.  Note that I switched back to the previous 
kernel, but it's running the same module list and I tried to point 
ksymoops to the correct pieces.  I also typed the oops message in from 
what I wrote down from the screen.  Please let me know if I made a 
mistake there.
