I have seen both a trap 12 and a trap 9 from a Friday Feb. 2 kernel.  This is
occuring on my laptop (AST Ascentia 810N) which I can't seem to get to create a
core dump.  Here is a hand transcription of what I see.

Mounting root from ufs:/dev/ad0s1a
pccard: card inserted, slot 0
pccard: card inserted, slot 1
kernel trap 9 with interrupts disabled

Fatal trap 9: general protection fault while in kernel mode
instruction pointer   = 0x8:0xc0270ad8
stack pointer         = 0x10:0xc2fb4f50
frame pointer         = 0x10:0xc2fb4f64
code segment          = base 0x0, limit 0xfffff, type 0x1b
                      = DPL 0, pres 1, def32 1, gran 1
processor eflags      = resume, IOPL = 0
current process       = 16 (irq14:ata0)
kernel: type 9 trap, code=0
Stopped at      sw1b+0x77:  ltr   %si

sw1b(4000) at sw1b+0x77         (note this is actually swtch())
ithd_loop(0,c2fb4fa8) at ithd_loop+0xf7
fork_exit(c0275bd0,0,c2fb4fa8_ at fork_exit+0x2d
fork_trampoline() at fork_trampoline+0x8

I don't have WITNESS or INVARIANTS at this time and don;t have a serial console
so I can't capture the output.

I can try adding these to my kernel and transcribe a little bit by hand.  I can
also send my kernel config and dmesg from a Nov kernel which boots.
