I'll comment, although it doesn't totally apply, because I've only
done this on NetBSD-current (I have never run FreeBSD-current, and I
have never had reason to do a make world on the 2.1.0 and 2.1.5
systems I've run), which doesn't have John's VM work.

I usually see these kinds of problems when I have bad RAM, or the
cache or RAM timings are too aggresive.  If this is a new problem,
with hardware that hasn't been changed in awhile, however, this may
not be your problem.

This is the exact hardware one of my NetBSD machines is (well, it had
a BT956c and/or an Adaptec 2940UW, depending on when it was run, and
the drives were different... OK, almost exact...).  I've also spent
lots of time tweaking on my AMD 5x86/133 (formerly AMD 486DX2/80),
EISA bus machine.
