I've got a nice notebook here (Pentium MMX 233, 48M RAM) that I'm trying
to get NetBSD to behave on.  However, I'm seeing symptoms reminiscent of
memory problems on it; at seemingly random intervals, programs will dump
core.  A favorite one is cc1 (or cpp), when I'm trying to compile a
kernel.  Sometimes, cc1 will dump core at a certain spot in a certain
file, and then if I run cc again on that file, it'll fault in the same
place.  Other times, when I run cc again, it compiles that file just fine.
Occasionally, I'll get kernel panics.  So far, I think I've only gotten a
Page Fault Trap panic, but I could be wrong.  Below is the dmesg output
from the machine.

Any ideas what I should try next?

Chris
