Hey folks ... I am putting my two cents that I am seeing the same error message with the following setup:
- Lenovo X1 Yoga - Intel HD520 Graphics - Onelink+ docking station with two Displayport connected monitors - Ubuntu 16.04 - Tested with following mainline PPA kernels (4.4.x, 4.6.x, 4.7.x, 4.8.x, 4.9 RC6) The issue persists in what appears all kernel branches from the mainline builds. Below is the syslog message from my test with 4.7.6 kernel from mainline from this morning: Nov 22 10:31:46 mikrobi-x1 kernel: [ 51.190096] [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR*

failed to train DP, aborting Willing to test and produce other logs to help with the resolution of this issue as I would rather NOT use the docking station as paper weight. The issue does not persist when connecting to the Displayport on the laptop itself. Just when using the external docking station. Furthermore, when using the laptop Displayport or the main LCD display, no other issues to be reported. Some other i915 bugs report issues with blinking or freezing, but I experience none of that when using the main display or the Displayport port on the laptop itself.
