Ddb prompt halts

["Bo Byrd" <bo@bbyrd.net>]

My OpenBSD 3.1-stable machine (toshiba satellite pro 4300 laptop) keeps
abruptly halting to the "ddb>" prompt.  This is the message it gives:

kernel: page fault trap, code=0
Stopped at _wi_init+0x7bd: movw 0x828(%edx, %ecx,1),%ax

The system had uptime greater than 200 days (I was going for a record)
and worked flawlessly until now.  I can duplicate the problem by using a
wireless XP laptop's "XP remote desktop client application" to connect
to another xp machine on the wired portion of my network.  The OpenBSD
laptop has a wi0 wep-128 card in it running hostap mode to a single
winxp client laptop running wep128....any ideas?  Syslog isnt showing
anything unusual... My dmesg follows.

Thanks,
Bo Byrd
