[Bug 1525390] Re: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A

 

** Description changed:

  Dell 3552 Inspiron laptop, bouth with Ubuntu 14.04LTS upgraded, to
  15.10.
  
  Every few minutes the following appears in the syslog:
  [ 6355.488381] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=1171 end=1172)
- 
- accompanied by a failure of the wifi network. The network stack must be
- manually reset to restore function
  
  
  Does not seem to be related to any specific user activity, though I note the Chrome 47 displays many graphical artifacts in images.
  Additionally, the below stack trace often appears:
