I commented out the fstab entry for the filesystem, then ran xfs_repair
which now does not hang and gives the following output:

think# xfs_repair /dev/hda4
Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ERROR: The filesystem has valuable metadata changes in a log which needs
to
be replayed.  Mount the filesystem to replay the log, and unmount it
before
re-running xfs_repair.  If you are unable to mount the filesystem, then
use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a
mount
of the filesystem before doing this.


I ran xfs_logprint and the output is extremely long.  I have attached it
rather than include it here.
