Unfortunately i can not get it to -suse, since i don't have any access, so
it will probably still be up to you to do that. But i will attach the
patch against the suse kernel tree to the bug report. We can, however,
also just fix it upstream and 10.3 will just get it. It _is_ easy to
work around on 10.2 (shutdown method = shutdown).
BTW: i am not too sure about that ENODEV, i just took the first error code
that came to my mind. But if nobody objects.... :-)
