It would be nice if you could try it down to the PMU driver missing that event or some race going on in the input layer. I've improved the PMU driver locking so that it does some flip/flop of input buffers to avoid filling up the PMU's own event queue, but there may still be a different problem I didn't find yet. Ben.
