hm, that's all a bit strange. It would be better to do the
request_region() just once and if that works, retain the reservation rather
than releasing and reacquiring it.

That being said, the code you've modified is disabled due to
!defined(PnPWakeup), and the chances of anyone ever changing that are close
to zero.
