Hmm... lots of code=0 and qualifier=0... this looks like something
non-standard ;-)
I did not look this up in the SCSI specifications (you should find them
at www.t10.org) but I suspect there's something wrong with your OS, SCSI
driver, or mtx. Or, perhaps, /dev/sg0 is not an autochanger now (this
can happen).

Ok, this usually means there's no tape loaded into the drive.
After getting mtx working try to load a tape using mtx and retry the 'mt
status' command. It should give some more useful information.
If it doesn't, but does after a while, there's a timing problem in your
mtx-changer (most easily fixed by enabling the wait_for_drive function
in mtx-changer).

That's ok, as mtx needs a raw SCSI device to work with, not the tape
drive interface. Still, I/O error here looks suspicious.
Does your system have an lsscsi command?
