What sort of tape is this? DDS, QIC? QIC support is BAD in NetBSD's tape
driver.

What scsi driver did you use? Contrary to ncrscsi, sbc does not do
disconnect-reconnect, and during long tape operations, you may run into a
timeout.

From Espresso's kernel config:

# SBC_PDMA      0x01    /* Use PDMA for polled transfers */
# SBC_INTR      0x02    /* Allow SCSI IRQ/DRQ interrupts */
# SBC_RESELECT  0x04    /* Allow disconnect/reselect */
sbc0            at obio? flags 0x1      # MI SCSI NCR 5380

-- can someone with commit rights please add the flag values to GENERIC?
