Not sure. It follows a
"Clock recovery check failed, cannot continue channel equalization",
which AFAICS appeared recently, first in CI_DRM_1655. The error message
itself isn't too old either though, it was added in CI_DRM_1626
("drm/i915: Make DP link training channel equalization DP 1.2 Spec
compliant").
