--- Comment #37 from Alex Deucher agd5f@yahoo.com 2011-07-07 14:25:29 PDT --- Maybe we should try and sort out why there is so much latency in the interrupt handler for Simon rather than rewriting the entire thing. Or we could just use the pflip interrupts where they are working and use the existing code on older asics.
