A directory block has an entry that is not in the hash index.
Either there's an underlying corruption on disk, or there's an
inconsistency in what has been logged and so an entire change has
not been replayed. Hence the post recovery verification has thrown a
corruption error....

If you haven't already repaired the filesystem, can you send me a
metadump of the filesystem in question?

I'm not sure what this has to do with the XFS problem - it's
apparently stuck in invalidate_bh_lrus() walking a CPU mask....

Cheers,

Dave.
