I used to have lots of problems with the NCR chip with both 1.3.3 and the
19981016 snapshot with either an old 1Gb or a modern 4Gb SCSI drive
internally or externally.

I then changed the 74F623 as per:

http://www.netbsd.org/Ports/alpha/faq.html#multia-heat-death

and I havent had a NCR problem since and the system has now been up for
over a month.

Dont know if the NCR chip is affected by heat possibly or if it's totally
unrelated but it certanily solved all my problems.

Cheers
Kev
