the command to the drive even before it sees the DMA start. When there
are very fast drives connected to the controller, or when the data request
hits in the drive cache, there is the possibility that the drive returns a part
or all of the requested data to the controller before the DMA start is issued.
In this case, the controller would become confused as to what to do with the data.
In the worst case when all the data is returned back to the controller, the
controller could hang. In other cases it could return partial data returning
in data corruption. This problem has been seen in PPC systems and can also appear
on an system with very fast disks, where the SATA controller is sitting behind a
number of bridges, and hence there is significant latency between the r/w command
