    SubjectRe: ISA DMA controller hangs
    So how do we solve this problem? We should do a master clear and then
    enable channel 4 after a suspend. The question is where. I see three
    possible places:

    * In the suspend code in kernel/power.
    * In the driver actually handling the suspend (ACPI/APM/etc.).
    * Via the device layer by adding a device for the DMA controller.

    Which would be the preferred solution?
