I've got a machine with an ATAPI Seagate 10/20 Travan tape drive. It's
running 1.6.1. If a tape is in the drive at boot time, the kernel panics.

st0 st0(pciide0:1:1) polling command not done
panic: scsipi_execute_xs

The trace is:

scsipi_execute_xs
atapi_scsipi_cmd
scsipi_command
scsipi_test_unit_ready
stattach
st_atapibus_attach
config_attach
atapi_probe_device
etc...

Is there a quirk that can be added to stop this blowing the machine
away? The drive works fine if a tape is not present at boot time.
