NetBSD server 3.0_RC6 NetBSD 3.0_RC6 (SERVER) #2: Tue Dec 13 18:50:22 GMT 2005  glenn@server:/usr/src/sys/arch/i386/compile/SERVER i386
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.
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.
At present downgrading to 2.0.2 seems to be the only solution...
