    SubjectRe: [2.4.20][2.5.60] /proc/interrupts comparsion - two irqs for i8042?

    It's a new OSS Sound Blaster driver from Paul Laufer along with the new
    PnP changes from Adam Belay.

    Things are looking better but we still have serious conflicts. I don't
    know why i'm out of IRQs so quickly.

    The counter is at zero because it was a fresh remote reboot. If i was to
    use the soundblaster I would get IRQ/DMA timeout errors. I do hear chunks
    of sound though so we've got a conflict of sharing IRQs somewhere.
