You should get that output on your console (and in your
/var/log/messages), do you?

This can be due to a number of reasons, the most common being using
the wrong major number for /dev/xfs0. Have you double-checked that
it's correct?
Otherwise, I suggest applying the appended patch and see if it gives
you any better hint as to what could be wrong.

Thanks for your patch. I have installed it.
