John Baldwin told me there is standing problem with APICs on 7500SW2 motherboards. Possible solution he suggested was: > You can try to change bus_clock from 66000000 to 533000000 in sys/i386/i386/mpapic.c and see if that helps. This didn't help me (I couldn't even pass "panic (y/n)" with "no"). See if it helps you. What really concerns me now is 5.0-RELEASE with all the SMPng can't cope with the problem.
