[drm:intel_dp_detect [i915]] *ERROR* LSPCON init failed on port D

Description of problem: Computer tends to freeze from time to time for short periods, especially when starting Steam. It is impossible to play games, especially "Nier: Automata". The freezes seem to correlate with listing appearing in the logs:

Possible to encounter also when running Steam application.

Actual results: System freezes briefly from time to time. Games are unplayable.

Expected results: System stops to freeze. Games are playable.

Additional info: Game unplayability may be related to something else. However brief freezes certainly are related to drm.
