    Ok, actually: first - sorry for the scattershot replies. I thought
    userspace was updated earlier, but:

    xfsprogs-2.10.1 (5 September 2008)...
    - Add packed on-disk shortform directory for ARM's old ABI, thanks to
    Eric Sandeen.

    and the original kernel change:

    [XFS] Pack some shortform dir2 structures for the ARM old ABI
    Note that userspace needs a similar treatment, and any filesystems which
    were running with the previous rogue "fix" will now see corruption

    So perhaps as a first easy test, can you please re-test with
    xfsprogs-2.10.1 or newer.
