[drm] *ERROR* failed to enable link training
The symptoms I observe: plugging in/out USB-C to DP cable has zero effect.
The first occurrence of subj error is at Mar 17 11:15:53 nixps kernel: i915 0000:00:02.0: [drm] *ERROR* failed to enable link training
(this happened after I unplugged DP cable to charge the battery and once I plugged it back it stopped working)
PS: I'm debugging another drm related issue ([drm] *ERROR* CPU pipe A FIFO underrun
) so the log file might be a bit bloated.
