What is strange is that at this point the ioctl has already 
been invoked several times...

Error 5 is EIO btw, and dump doesn't stop on QFA errors, it
ignores them (after all QFA is not required to restore the tape).

The second error (the write error) is happening on a write
on a tape and you get a second EIO. 

Could this be a bad tape ? Try to write less data to the tape
for example, since the error seem to happen through the end of
the tape.

mt stoptions scsi2logical

you can also pass some options to the kernel st driver when
you load it.
