SubjectOops on linux 2.4.20-ac1
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.

ksymoops 2.4.1 on i686 2.4.19. Options used
