Description Martin Peres 2017-06-20 13:15:34 UTC
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:

It all looks like the fi-skl-6700hq is dying slowly but surely :D

No need to ask QA to verify, so forcing to CLOSED.
