    First, the two devices in question are not on the same interrupt. Second, it
    is very difficult in this day in age to build a system without interrupt
    sharing. While I agree that it's better to have as few devices sharing as
    possible, there are simply too many devices in modern systems and too few
    interrupts. Interrupt sharing needs to work on modern hardware and needs to
    work in Linux. This notebook is pretty typical in its interrupt distribution
    and I'm not certain that this is a problem. In fact, while many devices on
    this system use IRQ 11 the only one active at the time was the audio
    controller. And while IRQ 10 is shared between the CardBus adapters and the
    video card the problems still occur if I don't run X and video interrupts
    shouldn't be generated in console mode, right?

    There are no options in my notebook's BIOS to reconfigure interrupts or
    disable
    devices.

    Attached.
