[ Correct linux-pm ML and add Mika & Jani ]
Thanks for the feedback.
There are some cpu/hotplug fixes post-v4.10-rc1. Give that a try.
Yesterday, after answers from drm-intel folks I have seen that a cpu/hotplug commit [1] was reverted in drm-intel.git#drm-intel-nightly. I haven't tried that.
It's good when Thomas knows of this and gets in contact with drm-intel folks.
