There are a couple of commits that are the *messenger* here that this will bisect to, but must not be reverted: commit d4cb3fd9b548b8bfe2a712ec920b9ebabd3547ab Author: Matthew Auld <<a href="mailto:matthew.auld@intel.com">matthew.auld@intel.com</a>> Date: Wed Oct 19 22:29:53 2016 +0100 drm/i915/dp: add lane_count check in intel_dp_check_link_status and related commit dd788090822300a66ff469ae9e50f6d28d124eb8 Author: Ville Syrjälä <<a href="mailto:ville.syrjala@linux.intel.com">ville.syrjala@linux.intel.com</a>> Date: Thu Jul 28 17:55:04 2016 +0300 drm/i915: Warn about aux msg buffer vs. size mismatch Apparently there was a commit to mitigate related problems in commit d626f34573551479f62b09d4df09efc4af88136d Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Tue Jun 21 09:16:53 2016 +0100 drm/i915/fbdev: Perform async fbdev initialisation much later Possibly the problem wasn't introduced not so much by async fbdev but rather changes in intel_dp_detect.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
