It works for me under 2.2-stable using an AHA-2740, and until very
recently under CAM using the ASUS-875. Under CAM, there were "ignored"
messages:
ILLEGAL REQUEST asc:24,0 on open, and
ILLEGAL REQUEST asc:26,0 on close
(or equivalent - they might have been slightly different).

The 'mt -f /dev/nrst0 blocksize 512' fails. Curiously, the debug output
(attached) finishes by complaining that it was unable to set
variable blocksize.

P.S. I did not mean to insult you! I know d****d well that you tested
the code to exaustion on the drives available to you. It
just doesn't work at all for me on my drive...
What stings, is that it DID :-}
