>Description:

My SCSI exabyte tape drive no longer works.  I was previously running a kernel
from -current not long after 1.0, and it worked.  At a previos boot I got this:

uha0 at isa0 port 0x330-0x33f irq 11u14_init: lmask=d1, smask=81

scsibus0 at uha0
uha0 targ 0 lun 0: <MICROP, 1598-15       GP, DG03> SCSI1 0/direct fixed
sd0 at scsibus0: 991MB, 1928 cyl, 15 head, 70 sec, 512 bytes/sec
uha0 targ 4 lun 0: <EXABYTE, EXB-8200, 254D> SCSI1 1/sequential removable
st0 at scsibus0: st0(uha0:4:0): illegal request, data = 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
drive empty
st0(uha0:4:0): not ready, data = 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
st0(uha0:4:0): not ready, data = 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I believe the "not ready" msgs came when I tried to read from the drive
with tar and got EIO.

I just rebooted and got this:

scsibus0 at uha0
uha0 targ 0 lun 0: <MICROP, 1598-15       GP, DG03> SCSI1 0/direct fixed
sd0 at scsibus0: 991MB, 1928 cyl, 15 head, 70 sec, 512 bytes/sec
uha0 targ 4 lun 0: <EXABYTE, EXB-8200, 254D> SCSI1 1/sequential removable
st0 at scsibus0: drive empty

(the drive is not empty), and tar still gets EIO.
