    Please for the Linux booting Linux scenario it is mandatory we get this right
    for reboot. I know for a fact that currently we leave active receive buffers on
    network cards when we reboot. (If you haven't downed the interface). So it
    is possible for a network packet to come in and hose a machine that is rebooting.

    Occasionally I test my linux booting linux code by loading memtest86 to make certain
    I don't have something like that going on. And the first time I tried it I hadn't
    downed the interfaces and I actually saw a network packet come in and corrupt
    memory. I also have similar reports from other about disk subsystems.
