A device timeout occured (i.e. the sa driver had to wait too
long for the device to respond), so the driver assumed that the
drive went out for lunch, and it sent a reset command to try to
bring it back.
This could happen, for example, if the drive spends too much
time trying to correct a read error, or if rewinding the tape
takes too much time, or things like that. It could indicate a
firmware or hardware error (termination etc.), too.

Oliver
