this is just a quick "me too"-message; one of our customers (also using a 
modern LTO drive, btw) is having the exact same results. In his case, though, 
the problems occur rather frequently.

We are having difficulties debugging the problem sensibly, as the concerned 
server is in full production (for quite a number of other services).

No modification of tape behavior via stinit. Is there any sensible way to 
request the configuration data from the drive? The ones mentioned in the "How 
to test the drive" chapter do not seem to work for me; mt stsetoptions does 
not result in any output in the system log/dmesg.

Thx
   Bastian
