I have seen this a couple times... it has happened when reading off my nec-210 cd-rom drive via nfs... the cdrom is connected to a 8bit controler based on the ncr53c400 by nec... I am using the nca driver... I'm not sure if this is related...

So I don't suppose this to be a problem caused > by the driver. well... now you have another report... just a bit about my machine... it has 8megs ram... running a 486/33dx running at 40mhz... the only thing on the scsi controler is the cdrom... hope this helps...
