    SubjectRe: Warn about taskfile?

    If your corruption is only under DMA you have a chipset or an ./arch/
    problem. If you have corruption under PIO, this could be a timing error.
    If command mode of taskfile is at issue, you can not function period.

    If this only happens on writes, you have a FIFO problem in the ASIC or
    iotable for the scatter gather formation.

    Taskfile is not broken, it is the only means to talk to an ATA/ATAPI/SATA
    device. How Taskfile is executed is dependent on the device attached.

    So if this is the x86-64 issue you have to fix that arch.
