    Subjectxfs bug in 2.6.26-rc9

    I received this when running xfs_fsr to defragment my xfs volume (which
    resides on a crypted lvm).

    Could it be that something is wrong with my xfs volume and this is not
    being properly handled (since it seems to refer to getbmap below?).

    Kernel is configured with oldconfig from ubuntu hardy stock kernel plus
    Alsa. Hardware can be seen at
    <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/235074>.

    Kernel oopsed (caps lock+other flashing when I woke up this morning),
    don't know if it's related to the below bug or if it's something else.
    Screensaver was on so I couldn't see any text to see more info.
