OK, this happens now:

VFS: Disk change detected on device sr(11,0)
scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 1, lun 0 Read (10) 00 00 00 00 00 00 00 01 00

Hang on... I just tried it again and it works. I don't think i've got a
termination or SCSI ID conflict, but the following looks wrong:

(scsi0:0:2:0) Synchronous at 5.0 Mbyte/sec, offset 8.
  Vendor: HP Model: HP35480A Rev: 1109
  Type: Sequential-Access ANSI SCSI revision: 02
Detected scsi tape st0 at scsi0, channel 0, id 2, lun 0
  Vendor: HP Model: C1130A Rev: 3540
  Type: Processor ANSI SCSI revision: 02

Shouldn't there be a line similar to:
(scsi0:0:2:0) Synchronous at 5.0 Mbyte/sec, offset 8.

but for the scanner?

I'll unplug the scanner and try again. Perhaps it's not internally
terminated like i assumed (but then why does my DAT and the scanner work?)

And it seems that inserting the smbfs module locks everything up completely
but that's not SCSI related.
