Commit e9eb8388306364295308132265c00bea685f409f ("ide: respect current
DMA setting during resume") breaks resume on my PowerBook G4.

I get a stream of the following:

hda: task_out_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_out_intr: error=0x04 { DriveStatusError }
ide: failed opcode was: unknown

and generally the machine hangs, although once it reported

ide0: reset: success

and resumed successfully.
