One hour GPF in 2.0.24

Hello again... I am running the 2.0.24 kernel and have been having
serious problems idling. After approximately 58 minutes of no keyboard
activity I get a general protection fault which kills off kerneld. I
have tried everything short of hacking the kernel myself (which I
probably should have tried), including a completely barebones kernel
without module support, and without APM support. After the GPF, mv and
cp have core dumped on me and many other non-pleasant situations have
plagued me. I realize most of the development effort is going into the
new kernels, but I am dying to have linux stable again. Below is a dump
of my hardware followed by the /var/log/messages dump of the GPF itself.
I would be willing to recompile my kernel all day long to test things out
if someone can get this fixed! I apologize for the size of this email, but
I think all information here is atleast mostly relevant:
