I'll attach a dmesg output to this message, hopefully that'll help. I
tried dropped hw.pcic.intr_path=1 into loader.conf and rebooting. That
seems to have helped, though I'm not 100% the wi card is happy right
now, since I don't have an AP here to test with.

The problems occured while I was at home using the wireless ethernet
and attempted to talk to my GPS via the serial card. If I wasn't
talking to the serial device it seemed to do okay.
