I have:
Bus 0, device 14, function 0:
SCSI storage controller: NCR 53c895 (rev 1).
Medium devsel. IRQ 11. Master Capable. Latency=64. Min Gnt=30.Max Lat=64.
I/O at 0xdc00 [0xdc01].
Non-prefetchable 32 bit memory at 0xdfffef00 [0xdfffef00].
Non-prefetchable 32 bit memory at 0xdfffd000 [0xdfffd000].
and got ~same behavior when I connected an external tape drive, I
tested tree cables without resolving it.
I had an extra internal terminator so I attached an extra cable after
the drive and then the internal terminator, and now it works without
any problems.
So I would guess you have bad cable/terminator in some combination.
Regards,
/Karl
