If something is sharing an IRQ with some component of your I/O
devices, what you saw can easily happen. This was my experience when
capturing video, for example: every slot in my box is full, and the
IDE RAID card to which I was capturing the video shares IRQ 11 with my
sound card (which was capturing the audio portion of the video) and
with my SCSI adapter. Under very heavy load, I was getting numerous
crashes that all pointed into UFS/VFS. In my case, capturing 320x240
instead of 640x480 "cured" the crash, but that's really just a bandaid
to lower the load to the IDE RAID.
