Try running xfs_logprint -t on the filesystem, xfs_logprint on its own
is not quite smart enough to work out which parts of the log have been
written to as part of the last mount, and which have not. After a clean
unmount you should get this type of output:

[root@laptop lord]# xfs_logprint -t /dev/hda8
xfs_logprint:
    data device: 0x308
    log device: 0x308 daddr: 7654976 length: 12000

    log tail: 11364 head: 11364 state: <CLEAN>
