I can see the same dmesg output when (un-)plugging DisplayPort cable from X200s
(GM45 chipset) docking station a few times - no hangs though:
[ 178.049984] [drm:intel_dp_start_link_train] *ERROR* failed to enable link
training
[ 178.052592] [drm:intel_dp_complete_link_train] *ERROR* failed to start
channel equalization
[ 194.914411] [drm:intel_dp_start_link_train] *ERROR* too many voltage
retries, give up
