>Description:
During hardware probe, or when rescanning SCSI bus, attempting to detect a SCSI tape drive (Freecom/HP DAT-72 DDS-5) fails with "SCSI opcode 0x12 timed out" on NetBSD 2.1 or later.

Have tested this with 2.1, 3.0 RC5, RC6 and 3.0 using Tekram DC-395UW SCSI card. Downgrading to 2.0.2 solves problem.
>How-To-Repeat:
Connect a tape drive to SCSI bus - not sure if problem is with trm or st driver though. Have not been able to test with alternative SCSI card.
>Fix:
At present downgrading to 2.0.2 seems to be the only solution...
