Hi Ferenc,

This gfs hang on failed mounts is documented in bugzilla bug #425421,
and I've already got a patch for it.  Since this bug was reported
internally to Red Hat, I don't know if this bug record is viewable by
the public.  (I don't have control over the permission bits and how
they default, so don't shoot the messenger.)  :7)  The fix has not been
shipped yet due to code freeze, but I'll attach the patch that fixes 
it below.

Regards,

Bob Peterson
