In any case, I would like to think that "read the source, Luke" is the right answer. So, while I am in the asking mode, is there a simple way to turn off the PIT interrupt without changing the PIT program? I would like a way to stop the interrupts AND also stop the NMIs that it generates for the watchdog. I suspect that this is a bit more complex that it would appear, due to how its wired. -- George Anzinger george@mvista.com High-res-timers: http://sourceforge.net/projects/high-res-timers/ Preemption patch: http://www.kernel.org/pub/linux/kernel/people/rml
