For what it's worth, I'm seeing similar problems on a laptop with Mobile
Pentium IV processor, only when doing large compiles.  They started
after a build/installworld after a cvsup on 20 September.  Swapping
memory out had no effect.  (The BIOS has no memory timing options that I
could find.)

(The problem was partially masked by the cc/cpp0 problem that also
showed up in that cvsup, but which has been since resolved; I got around
that one by building the new world with gcc 3.1 from ports and then
rebuilding with the base cc ASAP after the installworld.)
