drm errors in journal

the command

 journalctl -p 3 -xb 

gives (among others) the following

kernel: [drm:skl_set_power_well [i915]] *ERROR* power well 2 disable timeout
kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=59427 end=59428) time 174 us, min 1430, max 1439, scanline start 1428, end 1444
kernel: [drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]] *ERROR* [CRTC:32:pipe A] flip_done timed out
kernel: [drm:i915_gem_idle_work_handler [i915]] *ERROR* Timeout waiting for engines to idle

is there anything I should do?

Re: drm errors in journal

You really need to provide more info (hardware details, what you tried, etc.)

A quick google search gave a few suggestions: try booting with i915.enable_rc6=0 or with i915.enable_psr=0
