FreeBSD 8.1-STABLE sometime after 10/28/2010 has caused a fatal boot =
error on my Toshiba U205, 1.8 GHz Core Duo laptop.

Many times every week I sync with STABLE and build everything.  I have =
been doing this for years.

I sync'd (via csup) and built on 10/28/2010 and everything was fine.

Then I sync'd yesterday 11/1/2010 and it crashes on boot.  The =
diagnostics print out the following:

---

Fatal trap 18: integer divide fault while in kernel mode

kdb_backtrace
panic
trap_fatal
trap
calltrap
topo_probe
cpu_topo
smp_topo
sched_setup
mi_startup

---

I reverted at the loader via boot /boot/kernel.old, resync'd today, =
rebuilt, and things are still broken.

Any ideas?
