--- Comment #2 from Ed Maste <emaste at freebsd.org> ---
The common errors from the log:
4352 t520 kernel: error: [drm:pid1064:__gen6_gt_force_wake_get] *ERROR* Timed
out waiting for forcewake to ack request.
4155 t520 kernel: error: [drm:pid1064:__gen6_gt_wait_for_thread_c0] *ERROR* GT
thread status wait timed out
4145 t520 kernel: error: [drm:pid1064:gen6_gt_check_fifodbg] *ERROR* MMIO read
or write has been dropped 3
Does this happen before / after suspend+resume (or both)?
