I'm happy (yeah right) to report that your not the only one.

After changing my kernel config to add the 4BSD scheduler and PREEMPTION
options on my Ultra10 and rebuilding the kernel. I put the machine on a
make -j 2 buildworld. 

After I got back from school I found the machine totally wedged, not a
kernel panic or any thing on the screen (I run with a monitor and
keyboard attached).

Only local applied patches are the cs4231 driver that Pyun YongHyeon
ported.
