I just rebuilt my GENERIC.MPDEBUG kernel from today's current.  On boot,
I'm getting a page fault as follows:

...
pchb2 at pci0 dev 17 function 1
pchb2: ServerWorks PCIHB5 (rev. 0x02)
pci3 at pchb2 bus 3uvm_fault(0xc07875e0, 0, 0, 1) -> 0xe
kernel: page fault trap, code=0
Stopped in pid 0.1 (swapper) at netbsd:mpbios_pci_attach_hook+0x47:	repe
cmp sb	(%esi),%es:(%edi)
db{1}>

I see there have been some recent changes to the mpbios stuff, so I assume
this is related.  This system booted up fine with a current kernel from
about a week ago.

If a backtrace or anything else is needed, let me know and I can get it. 
Speaking of backtraces, how would I save the backtrace without typing the
whole thing over again?


Thanks.
