Description Marta Löfstedt 2018-01-29 08:40:49 UTC

<7>[  383.652823] [drm:intel_dp_start_link_train [i915]] Clock recovery check failed, cannot continue channel equalization
<3>[  383.652925] [drm:intel_dp_start_link_train [i915]] *ERROR* [CONNECTOR:77:eDP-1] Link Training failed at link rate = 540000, lane count = 4
Comment 1 Marta Löfstedt 2018-01-29 08:44:45 UTC
Note, bug 104827 have similar error log in that case it is preceded by:

<7>[  312.395802] [drm:intel_dp_start_link_train [i915]] Channel equalization failed 5 times

I keep these 2 bugs separated until there is more data indicating that it could be the same issue.
