If so, do they have this problem too?
I think I saw this with 3.15-rc7 as well. Not so sure about 3.15-rc5. I now switched to acpi + ondemand governor which seems to work better, as I posted. I still hit cpu throttling, but well its hot inside here. And maybe the fan also needs some cleaning. Anyway, need to get some sleep now. I can test with rc7, rc5 and probably some older rc as I still have those available. Will take some time tough.
