Oh, I know that. But that is not of our concern - I believe we're discussing right now what to do when the lower, softer limits are reached and the thermal interrupt fires. When the hw forces HLT, it means we didn't do a very good job earlier, before it got so hot. :-) -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
