(It should be the > same as the kernel, since the code is the same.) OK, i tried your patch. Here's the result: uriah # camcontrol tur pt0 -v Unit is not ready (pass6:sym1:0:5:0): TEST UNIT READY. CDB: 0 0 0 0 0 0 (pass6:sym1:0:5:0): CAM Status: SCSI Status Error (pass6:sym1:0:5:0): SCSI Status: Check Condition (pass6:sym1:0:5:0): UNIT ATTENTION asc:0,0 (pass6:sym1:0:5:0): No additional sense information You're right, this rather seems to be a bug in the scanner's SCSI implementation. For comparision, i just issued a BDR to a less used disk, here's the result: uriah # camcontrol tur da3 -v Unit is not ready (pass2:sym0:0:4:0): TEST UNIT READY. CDB: 0 0 0 0 0 0 (pass2:sym0:0:4:0): CAM Status: SCSI Status Error (pass2:sym0:0:4:0): SCSI Status: Check Condition (pass2:sym0:0:4:0): UNIT ATTENTION asc:29,0 (pass2:sym0:0:4:0): Power on, reset, or bus device reset occurred Should/could we add a quirk for the scanner that synthesizes an ASC/ASCQ of 29,0 in that case? Here's the inquiry data: uriah # camcontrol inquiry pt0 pass6: <HP C2520A 3503> Fixed Processor SCSI-2 device pass6: 3.300MB/s transfers -- cheers, J"org .-.-. --... ...-- -.. .
