  GPIO?  That sure sounds like the driver is polling.  The driver source
confirms it.

  So I guess this explains the problem.  When tvtime is SCHED_FIFO, the
polling thread won't be allowed to run as often, and so events get
missed.  I don't know much about the kernel implementation of
SCHED_FIFO, but by the sounds of it I'm not sure if there is much that
can be done.

  Thoughts?
