>Description:
Quite suddenly in the last two weeks or so my previously functional
Symbios SC-875 card (NCR 53c875 based) has ceased to work with
OpenBSD. Fortunately all that is attached to it is a Win98 SCSI disk,
a ZIP Plus drive and my CD burner. Unfortunately this meant it went
for a few days to a couple of weeks before I noticed the problem. I
have been tracking current, with tree updates/rebuilds every week.
All of these devices continue to function when I boot to Win98 on
the SCSI disk attached to the SC-875.
During the boot I see the messages
CACHE TEST FAILED: ncr wrote 2, host read 1.
CACHE INCORRECTLY CONFIGURED.
During power up the card reports seeing all the scsi devices I have
attached:
