--- Comment #1 from Jani Nikula <jani.nikula at intel.com> ---
This is silly.

Based on the logs, I presume this happens before we enable eDP for the first
time:

-> intel_dp_detect
-> intel_dp_long_pulse
-> intel_dp_check_link_status (since it's eDP, connector status remains
connected)
-> apparently the crtc is active, but the channel eq is not okay, because well,
we've never trained before, and then we go on trying to retrain

Ander, any ideas when we caused this to happen?
