Does this partition, or a phisical disk below it, has, by any
chance, a spurious RAID signature?  This was not an issue in FC5 and
below.  If this happens to be the case then use 'dmraid -r -E ...'
to clean that up.  I bumped into that with "recycled" disks where I
was not even aware that some time in the past they were used as part
of RAID.  Somewhat nasty and it would be really nice to a clearer
indication what is happening instead of leaving that as a "dark
corner".

It will be "busy" once you booted with no outward indication
what makes that partition "busy" beyond that all 'open' calls fail.

See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=176623#c8

Maybe this is something else, but just an idea ...
