    The kernel stopped because it detected a disk buffer in an unexpected
    state. 2.6.12-rc5 kernel should contain some more fixes than
    for similar problems so you can try that kernel. If you are able to see
    the same problem with 2.6.12-rc5 then let us know please.

    Thanks for report
