    Here is the results of the first git bisect.
    The error message is different from the message
    subject, so I hope will be useful for you.
    Now, this box is crashing immediately after the
    network stack is up.

    PS: linux version shown by dmesg is 2.6.24 but it
    is the results of 'git bisect good v2.6.24' and
    'git bisect bad v2.6.25'

    Restarting system.
