I have the same problems (running on non-SMP works), but I kept quiet
because I cannot rule out hardware failure, yet. Memory is okay, but even
W2k crashes when (presumably) starting the 2nd CPU.

BSD will wreak havoc to the filesystem under even minor load, throwing
diverse signals to "make world", e.g. 6,10,11 before crashing in fs code
entirely, even resulting in soft-update inconsistencies :-/
IIRC I tried both DMA & PIO mode and two different controllers, I'm
currently planning to give the CPUs two a Linux-friend with the same
board (Gigabyte 6BXD).
Number crunching will *not* cause errors, though...
