>Description:
        NetBSD 1.5.2 + Exabyte 8500 won't report fileposition correct.
        On a tape with many backups it's rather confusing to not know..!
        This streamer works just fine (without this bug) on FreeBSD.

>How-To-Repeat:
	Install NetBSD-1.5.2 on IDE disc in a i386 machine with ISA 
        Adaptec 1542B
        Connect Exabyte 8500 externally. And insert tape.
        Rewind. Print status.
        Forward one file (on the condition that there is one on the 
        tape since before ofcourse :).
        Print status. And notice that's the same output.

>Fix:
        Most likely an error in the kernel, scsi-lib or the command (mt).
