Here is maybe an interesting observation.

This show all the times we have hit the issue:
http://benchsrv.fi.intel.com/cibuglog/?action_failures_history=399

for CI_DRM_3256 all occurrences are from shards-kbl2.
I am not saying that there is something particularly wrong with that machine. Which is clearly visible by looking at other runs.

There has been no linktraining issues on the KBL-shards since CI_DRM_3291 until CI_DRM_3304.

So, it appear as if:

unintentionally fixed something.
IGT-Version: 1.20-g1fc4de1c for both CI_DRM_3291 and CI_DRM_3292.

I will close this bug.
