Comment 6 James Ausmus 2019-04-25 01:18:02 UTC
Is this just a bad cable/bad monitor hooked up to re-icl-u? That's the only machine this issue is happening on, which makes me suspect a flaky piece of HW rather than a SW problem.

We need to check that as all issues are seems to be for DP:

<7> [175.115586] [drm:drm_dp_dpcd_access] Too many retries, giving up. First error: -110 <3> [175.115635] [drm:intel_dp_start_link_train [i915]] ERROR failed to start channel equalization <7> [175.115802] [drm:intel_dp_start_link_train [i915]] [CONNECTOR:196:DP-1] Link Training failed at link rate = 162000, lane count = 2

And on this system mDP is connected to Chamelium.

According to Imre no real user impact. Lowering priority
