>Description:
Most of the *sa0* tape devices respond to "not configured" when used with
the MT command. Any device that does not result in this message, hangs up.
The tape drive read light is on solid, but the drive motor is not running,
as far as I can tell. The MT command process is locked and can not be KILLed.
None of the *pass0* devices are "configured".
This same system and hardware worked under the previous V3.2 installation of
FreeBSD. The specific SCSI controller is an Adaptec 2902. While the
environment report above shows a modified kernel, this problem started after
the 4.1 upgrade, "out of the box".
>How-To-Repeat:
Turn on tape drive, install tape, execute MT command with one of the *sa0*
tape devices.
>Fix:
Reboot machine, turn off and do not use tape drive.
