I have been getting panics recently while trying to do installworld
while running
at single user on recent kernels.
Fatal trap 12: page fault while in kernel mode
mp_lock = 01000002; cpuid = 1; lapic.id = 00000000

I don't have a dmesg from the panicing kernel and kernel.old is from 29
Dec 1999.
I also don't have a crash dump (bad device name in dumpdev, now
corrected). I
will try to get these things, if I get a chance to try again. Things in
the
system:
SMP on Asus P2B-DS motherboard
softupdates on
usb recently enabled, but no peripherals yet
More information to follow...
