Lenovo X1 Carbon.
Ubuntu 14.04

Worked fine since early 2015. Last couple of weeks have not been able to
suspend/resume properly. First symptom was blacked-out menu text on windows.
Updated kernel to 4.4.0-38-generic; now session dies immediately on resume.
System runs OK while up, but have to shut down to transport.

   [drm] stuck on render ring
   [drm] GPU HANG: ecode 7:0:0x85dfbff8, in compiz [6944], reason:
         Ring hung, action: reset
