this is a well known problem, and we fixed it AFTER I made that
promouncement about it getting "as stable as its gonna get". It was fixed
by:
fsmp 1997/08/14 19:33:31 PDT
Modified files:
sys/i386/include smp.h
sys/kern init_main.c init_smp.c
Log:
The promised "better fix" for "Trap 9 When Boot SMP" problem.
We now tsleep() in kthread_init() between start_init()
and prepare_usermode() while waiting for ALL the idle_loop()
processes to come online.

for those shopping by "SNAP date" I would guess 970815 would be a
good vintage.
