I've installed FreeBSD 4.9-RELEASE on a Dell 400SC with an ATA Travan 
tape drive, accessing it through /dev/ast0.  On linear writing 
operations, it works great... but there appears to be some kind of 
timeout problem on rewind:

# mt -f /dev/nast0 rewind
mt: /dev/nast0: rewind: Input/output error

 From console:

Nov 12 11:28:02 bs4 /kernel: ast0: REZERO command timeout - resetting
Nov 12 11:28:02 bs4 /kernel: ata1: resetting devices .. done

This error does not appear if the tape is already rewound.  Any thoughts?
