I have encountered this error once before, and it meant that it timed out trying to access the disk/partition where swap was. It also coincided with a network card (fxp0) timeout, but I'm not sure that was related. The system was unresponsive from the console or remotely until it was completely power cycled, the reset button wasn't enough. > What is the causation for this error?

In my case, after some hair pulling, it turned out to be a bad SCSI cable. You might check your cabling and termination, and perhaps swap the cable even if it looks good -- mine looked better than the cable I replaced it with. Jim
