Hi, Is there a way to make the kernel HALT the CPU regularly even when it has got runnable processes? Sort of like increasing the idle thread priority? The problem is with one my computers which has a buggy CPU. No matter how many or how powerful fans I install, when there's a CPU usage of 100% for over ~5 minutes it just overheats and crashes the system. If the CPU usage on average never exceeds, say, 80%, the system keeps functioning just fine. Therefore it'd be a shame to throw the cpu out just for this reason. So is it possible to make the kernel always keep CPU usage lower than some value? Maybe without hacking the source? Atis
