Firstly, the patch adds an include to "iomap.h" - but this doesn't exist in stock 3.3. Simply removing this include seemed to allow the compile to complete successfully. With this patch applied (and not in DMA mode) I now get the following: - If I leave wake-from-suspend enabled for the serial port then it works correctly (i.e. no lost/extra 0x00 characters). - If I disable wake-from-suspend for the serial port and go through a suspend cycle (i.e. suspend and then wake), then the serial port starts to misbehave as before. - If I then re-enable wake-from-suspend and go through a suspend cycle it starts to work correctly again. So the problem is still that if wake-from-suspend is disabled for a serial port, and a suspend cycle is performed then when woken the serial port will not function correctly if operating in interrupt-mode.
