In the 3.2 version xfs_sync_flags does a double unlock of the ilock -
change the last argument of xfs_trans_ijoin from XFS_ILOCK_EXCL to 0
will fix this.  The 3.0 version doesn't have this bug.

And btw, the additions to the on-disk format are gross - this stuff
broke before and will break again when we add new features.
