Please file a bug at https://gitlab.freedesktop.org/drm/intel/issues/new Boot both kernels (revert vs. no revert), passing 'drm.debug=0xe log_buf_len=4M' to the kernel cmdline, and attach the resulting dmesg from each to the bug. Also would be good if you try to reproduce on the latest drm-tip (git://anongit.freedesktop.org/drm-tip drm-tip) as well. -- Ville Syrjälä Intel
