So feel free to merge that patch. There're still problems with Perfmon, but I'd rather wait until Stephane's new code is merged before addressing them. I've run withpreemption enabled on dual and single McKinley and on the simualtor and so far so good. I see interrupt latency variablilty drop from 4000--320000 cycles to 4000--8000 cycles, which is good. I don't yet see any major user-visible differences though. Peter C
