Since I just noticed that you posted the patches, did you find anything? From looking at it, if we preemption at 0, migrate disable at 3 then a substraction of one would underflow the preemption counter to f and migrate disable to 2. But based on code inspection mg should be at 1. And this does not explain where D & Z is coming from. > -- Steve Sebastian
