Screen flickers constantly in random intervals. Flickering does not appear while running windows or in bios. To describe "flick" - display or its part becomes black or filled with random pixels for a very short time. Sometimes "flick" appears more then once per second. When "flick" appears dmesg (with drm.debug=0xe) produces: ... birž. 19 21:29:04 localhost.localdomain kernel: [drm:drm_mode_addfb2 [drm]] [FB:74] birž. 19 21:29:04 localhost.localdomain kernel: [drm:gen8_irq_handler [i915]] hotplug event received, stat 0x01000000, dig 0x11101010, pins 0x00000010 birž. 19 21:29:04 localhost.localdomain kernel: [drm:intel_hpd_irq_handler [i915]] digital hpd port A - short birž. 19 21:29:04 localhost.localdomain kernel: [drm:intel_dp_hpd_pulse [i915]] got hpd irq on port A - short birž. 19 21:29:04 localhost.localdomain kernel: [drm:intel_dp_read_dpcd [i915]] DPCD: 12 0a 84 41 00 00 01 01 02 00 00 00 00 0b 00 birž. 19 21:29:04 localhost.localdomain kernel: [drm:drm_mode_addfb2 [drm]] [FB:72] ...
