How does that work?
In that particular instance, interrupts are still enabled and configured and will come in and be handled. It does not enable polling mode in that instance, and will run slowly if interrupts don't really work. That's the decision I made in that case. If the hardware advertises interrupts but does not support enable, I'd guess it still has interrupts. -corey ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
