-The ESP SCSI driver currently doesn't check whether a DMA requests has 
-completed before checking its status. On older qemu versions this works ok 
-because DMA happens instantly. On never qemu DMA can take an indeterminate 
-amount of time ooto complete, just like on real hardware.
-
-The patch below waits for the controller to raise the DMA interrupt after 
-initiating a DMA request.
