The machine fi-skl-6700hq started randomly generating the dmesg error message "[drm:intel_dp_check_link_status [i915]] *ERROR* Failed to get link status". First seen on IGT_1218 (based on CI_DRM_2742): http://benchsrv.fi.intel.com/archive/results/CI_IGT_test/IGT_1218/fi-skl-6700hq/igt@prime_busy@basic-wait-after-default.html This however does not seem to be due to an IGT change: http://benchsrv.fi.intel.com/archive/results/CI_IGT_test/IGT_1218/commits_short.log It all looks like the fi-skl-6700hq is dying slowly but surely :D
3 more test cases added: https://intel-gfx-ci.01.org/CI/CI_DRM_2746/fi-skl-6700hq/igt@prime_vgem@basic-sync-default.html https://intel-gfx-ci.01.org/CI/CI_DRM_2745/fi-skl-6700hq/igt@drv_module_reload@basic-reload.html https://intel-gfx-ci.01.org/CI/CI_DRM_2745/fi-skl-6700hq/igt@prime_self_import@basic-llseek-bad.html
This fixed the issue: c99a259 drm/i915/edp: Add a T12 panel delay quirk to fix DP AUX CH timeouts
No need to ask QA to verify, so forcing to CLOSED.
