I am having a very similar problem with a RH 6.2 box that I am working on
now.  After doing some research we are investigating  possible memory (RAM)
hardware issues.

Also you might want to check out
/usr/src/linux/Documentation/oops-tracing.txt
I was doing some reading in /usr/src/linux/Documentation/memory.txt

Hope this helps,

Jim

Subject: protection fault in kernel


Hi all!

I've installed RH linux in a hand-made computer (IDE disk, 4 serial
ports, parallel port, no floppy drive, no network) and am having a
protection fault randomly. I guess it is because of the hardware (the
people who did this computer use their feet instead of their brain to
think), but I'd like to know what is causing the problem so that I can
disable the faulty hardware.

This is the message I get from the kernel when it segfaults.
