Thanks. We got a bad batch of 68000's; I'm sure lots of people got them. The Seg-fault trap pushes the SP on the stack instead of the PC. Cute, huh? The bourne shell uses seg-faults to allocate memory. (It has to be heavily munged to work reliably with more than 200 bytes of shell variables.) Thus, context-switching crashes the kernel. Does your UNIX reliably crash on certain machines, but not others? Better check your 68k's!
