Starting with patch commit 9f836f9016ad5320e0c9230419d2102cf15a28aa Author: Patrik Jakobsson Date: Mon Nov 16 16:20:01 2015 +0100 drm/i915/gen9: Turn DC handling into a power well DPMS off operations may actually cause the entire system to powerdown or reboot. Disable power well support for now until Broxton gets fixes similar to what we have for SKL.
