kernel gives a bogus "hda: DMA disabled" message. I noticed that the 2.4.20-2.2
kernel gives a bogus hda: DMA disabled message, while it is actually enabled,
some scanning of the source found me this: in drivers/ide/ide.c
if (drive->autotune != 2) {
                /* DMA timings and setup moved to ide-probe.c */
                if (!driver->supports_dma && HWIF(drive)->ide_dma_off_quietly)
//                      HWIF(drive)->ide_dma_off_quietly(drive);
                        HWIF(drive)->ide_dma_off(drive);
                drive->dsc_overlap = (drive->next != drive && driver->supports_
                drive->nice1 = 1;
        }

Look at how for some reason a dma_off_quietly was changed into a dma_off without
beign quiet. Also notice that the code only checks for the availabality of
dma_off_quietly. I think this should be changed back otherwise you'll get lots
of support calls: why is my dma disabled???
