JFYI:

pluto2.freebsd.org (ia64) has been running reliably for a
long time with FreeBSD 6.x. Now that the machine has been
upgraded to FreeBSD -CURRENT do I experience machine check
aborts. These MCAs have been observed on pluto1.freebsd.org
for a while when it was running FreeBSD 7.x and it was
attributed to the hardware and Kris stopped package builds
on that machine.

Now I'm actually thinking that it's a FreeBSD problem,
because it now all of a sudden is a problem on pluto2 and
both machines are reliable otherwise -- that is, only
when doing a 4-way parallel package build do these MCAs
happen. An 8-way parallel buildworld is fine.

This does not mean that it's a hardware problem in your
case of course, but keep in mind that it may also be a
kernel bug...
