Well, there is no test for a "dead" NCR chip in the code,
so you can only have received a message from the timeout
handler, which warns if no progress has been made for some
time.

I have heard of just a few defective NCR chips over the last 
three years. Symptons were different: From complete failure
(system won't start with controller card installed) to a data
pattern dependent lockup (one NCR card could not extract some
NetBSD distribution file: Writing a certain data pattern lead
to a PCI bus error interrupt, and thus one file could not be
written to disk; replacing the NCR, card solved that ...)

Most of the problems I've heard of should have been covered 
by the SCSI card's warranty.
