Ah... I've seen something similar on some small memory (4M) machines I've
been trying to get running. I get lots of sig 11 (and sometimes
sig 4, illegal instruction, etc.) and thought it was hardware,
but swapping motherboards, cpu's, and memory didn't help.

Going from 4MB to 5MB reduces, but doesn't eliminate, the problems.

I'm running FreeBSD 2.1.0-R on a BEK-P405 PCI/ISA motherboard.
Chipset is ALI. On-board super I/O, WD Caviar 2850 (IDE), two NE2000
clone EtherNet cards, ISA VGA card (usually), also login prompt
enabled via on-board serial port. Sometimes booted diskless (in which
case there seems to be more random proc death, though it happens either way).
Swapfiles are big, at least 16Meg.
