Ah, no, it looks like this was a false alarm. I changed to a different
driver, and my SCSI problems are gone. It looks like they were due to
bugs in the AM53C974 driver. The wait-for-keypress thing was because when
it gets confused, it actually deliberately waits for your to press a key,
inside its interrupt routine (!), presumably as a debugging aid.
