Hmm... 3.0-current (supped 9/2/97), DPT RAID. fpx0, not a whole lot else.

I was using M$ Inetload 2.0 to simulate a bunch of mail users.   IT was 
running fine for a few minutes, then died horribly with:

Fatal trap 12: page fault while in kernel mode
cpuid = 1
lapic.id = 33554432

current process = Idle
mp_lock = 01000003

interrupt mask = net tty bio <- SMP: XXX

Stopped at _pmap_enter+0xa7:


and some other stuff.

The traceback is not too long, but I don't have any good way to type it
all in.

It goes like:

_pmap_enter
_vm_fault
Trap_pfault
_trap
_zalloc
_pmap_insert_entry
_pmap_enter
_kmem_alloc
_in_pcballoc
_Tcp_attach
_tcp_usr_attack
_sonewconn
_tcp_inut
_ip_input
_ipintr
swi_net_next


It is trivially reproducible at least on my hardware.
