    Seems I had this problem when compiling a custom kernel for an
    a7n8x board recently. hdparm couldn't enable the dma either. It
    finally worked after adding the correct IDE driver (amd/nforce)
    for that mobo. Until I corrected the problem disk performance
    was quite poor.

    You may need to compile a custom kernel with the correct driver for
    your motherboard. Or perhaps get try an updated kernel.
