from Harry Wentland
The kernel BUG should be fixed since 4.17 by this commit commit 20d4ac659c76034586a3ab79489b0940631a65de Author: Leo (Sunpeng) Li <sunpeng.li@amd.com> Date: Tue May 29 09:51:51 2018 -0400 drm/amd/display: Fix BUG_ON during CRTC atomic check update For cases where the CRTC is inactive (DPMS off), where a modeset is not required, yet the CRTC is still in the atomic state, we should not attempt to update anything on it. Previously, we were relying on the modereset_required() helper to check the above condition. However, the function returns false immediately if a modeset is not required, ignoring the CRTC's enable/active state flags. The correct way to filter is by looking at these flags instead.
