We had the same problem here. We found that it was caused by a bug in
chg-scsi. When the tape gets ejected, the program loops waiting for
function "SenseHandler" to return with code SENSE_NO_TAPE_ONLINE. The
generic SCSI version of this function can only return this code if it
was called with the parameter "flag" set to 2, telling it that the
device is a tape drive.Unfortunately that parameter is set to 0 when the
function gets called and returns with code SENSE_RETRY instead. Here
included is a patch that fixed the problem for us.
