    Looks like this box has been broken since December, 2006!
    Not booting unless "acpi=off" is a serious failure.

    Please get Linux up and running on the two boxes
    using whatever means are at your disposal (some mentioned
    in the thread above are acpi=off, pci=noacpi,
    pci=conf1, noapic hda=noprobe hdc=noprobe)

    Download the latest stable kernel ( today)
    Make sure that the latest kernel still fails unless
    you apply the workaround(s).

    Then open two a bug report for each machine here:

    Attach the output from acpidump, as well as the
    complete dmesg and lspci -vv output,
    and paste the contents of /proc/interrupts.
    Then, if you can capture the console output taken from the actual failure
    case, that would be ideal

    Lets see if we can find out what the problem is before we
    blacklist the machines.
