Hi Pablo,
looks like link training failure on eDP:
[16864.962219] [drm:intel_dp_start_link_train [i915]] Clock recovery check
failed, cannot continue channel equalization
Could you try the drm-tip branch from
git://anongit.freedesktop.org/drm-tip
(booting again with drm.debug=0x1e) and attach the dmesg log? Please also keep
the bootup messages in the log and also include the messages after you managed
to recover the display (by running xrandr or whatever was needed).
Thanks.</pre>
