    That option only works with multi-core AMD cpus, and only if the BIOS
    has not properly programmed the hypertransport bus's interrupt routing.

    There are issues with various motherboard chipsets and cpus that cause
    spurious interrupts, either due to bugs in the hardware, bad hardware
    design, bugs in the BIOS, or lack of documentation.  Unfortunately
    there is very little we can do about most of these issues.
