Panic "div_bind: inp == NULL" on -CURRENT from 02 Apr 2006

[I'm at least a week behind on mail -- just got back in town over the
weekend -- so if this has been covered, I apologize for the duplication.]

I've been tracking both RELENG_6 & HEAD on my laptop on a daily basis
for a while; I also try to track them on a weekly basis on my desktop at
work.  On 25 March, I had no problem doing that; on 02 April, RELENG_6
was fine, but HEAD hit a panic during the transition from single-user
mode to multi-user mode -- but only on my work desktop (my laptop
doesn't exhibit the problem at all).

I *suspect* -- based on the sequence of events -- that the initial panic
may well be associated with a NIC, and that the kbd driver gets a
secondary panic; regardless of what I suspect, the keyboard isn't usable
once the panic message spits out, but a serial console does work.

The nice thing is that the panic appears to be 100% reproducible; here
is a cut/paste from the serial console:

Dump complete
Automatic reboot in 15 seconds - press a key on the console to abort


At this point, I'll await suggestions.  I can make the dump available, I
expect, should that be useful.  I'm not sure how soon I will be able to
do much with my email backlog (which was at around 1K messages), so I've
set Reply-To to add an address for which I'll be monitoring mail more
closely during the workday.

Oh:  the local mirror from which /usr/src was updated had last been
updated a bit before 0400 hrs US/Pacific on 02 Apr 2006.

Peace,
david
