    Ok here we go,

    final results:

    2.6.8-rc1: OK
    2.6.8-rc2: OK
    2.6.8-rc3: OK
    2.6.8-rc3-bk1: OK
    2.6.8-rc3-bk2: OK
    2.6.8-rc3-bk3: OK
    2.6.8-rc3-bk4: OK
    2.6.8-rc4: BUG!

    So, assuming that everything went fine during testing, the bug got introduced
    in the transition between 2.6.8-rc3-bk4 and 2.6.8-rc4.
