I periodically get the following oops while playing quake, happens with both
the latest squake and qwcl (quakeworld). I can't really say what causes it
exactly, it doesn't allways happen, but it happens every few days.

Unable to handle kernel NULL pointer dereference at virtual address c0000003

Aiee, killing interrupt handler

at this point quake seqfaults, pppd stops working, and I have to kill it,
and re-run it, and the screen is left in graphics mode, so I have to run

My cpu is a cyrix 6x86 150+ 32 meg ram, 2 ide hard drives. This is my first
bug report, so please let me know if any more information is needed.
