Looks like you have some serious corruption; however your best bet would be
to boot knoppix and run xfs_repair (from the latest xfsprogs) package and
report back (preferrably with a strace of xfs_repair if its hanging).  In
addition, a metadump of the filesystem may be useful as well, Eric/other XFS
members can analyze why the mount is failing if they have that.
