I'll whip up a patch. I think we should cleanly stop the hardware in this case as well, for suspend to disk I think it can happen that we suspend the driver and then suspend is aborted. Not entirely sure about this though. Btw. What happens when we abort the DMA engine, reset the command pointer to a stop command, and start it again? Does it drain the FIFO properly?
