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.
