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. > [...crashdump deleted...] --=20 Chris BeHanna Software Engineer (Remove "bogus" before responding.) behanna@bogus.zbzoom.net Turning coffee into software since 1990.
