You can use kernel.old to compile a UP kernel. I always keep a UP kernel
around just in case. Also, when did your SMP box become unstable? There
was a known problem with SMP boxes when the vm page zero'ing during the idle
loop was first turned on that has since been fixed with the latest commit to
vm_machdep.c yesterday. Symptoms were frequent kernel panic 12's with
interrupts disabled .
