** Description changed:

  I'm trying triple monitor configuration on HD4000:
-  - 1650x1050 on VGA1
-  - 1920x1080 on DP2
-  - 1920x1080 on DP3
+  - 1650x1050 on VGA1
+  - 1920x1080 on DP2
+  - 1920x1080 on DP3
  
  Kernel hangs on boot if there is a monitor attached to DP2.
  
  If I attach monitor after boot, changing resolution on DP2 one CPU core
  becomes 100% busy with continuous errors:
  
  [drm:intel_dp_start_link_train], training pattern 1 signal levels 00000000
  [drm:intel_dp_start_link_train], training pattern 1 signal levels 02000000
  [drm:intel_dp_start_link_train], training pattern 1 signal levels 04000000
  
  BTW, Same triple monitor configuration works fine in Windows 7 so I
  assume that hardware is ok.
  
  Please advise what can be done next?
