Comment 5 for bug 1630774

This is a bug in the intel_powerclamp driver, please see following thread on LKML for details

https://lkml.org/lkml/2016/10/18/356

A fix is available here https://patchwork.kernel.org/patch/9365005/ this should make it's way to the stable releases, though I don't know when will it be available. Ubuntu folks might want to cherry pick it to release a kernel update

Thanks !
