I had some similar problems when I had a SCSI cd drive on an old isa
adaptec scsi card. It seems that the card was bad at handling certain
conditions, and the kernel drivers were bad at handling the card. I
finally "fixed" the problem with a new scsi card. Certainly using cat
as you do shouldn't cause any problems, so this does sound like either
a hardware or a kernel issue.
