[Bug 1529020] Re: Braswell: CPU pipe C FIFO underrun when mouse pointer changes display

 

apport information

** Tags added: apport-collected

** Description changed:

  Machine is a HP 250 G4 notebook with Celeron N3050, with BIOS F.1A Rev.A
  (latest).
  
  When I add a external display (VGA, 1920x1080@60Hz), sometimes when I cross over to it with the mouse cursor, it flickers (turns off for about 1-2 seconds), and I get:
  [  692.452293] [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe C FIFO underrun.
  It will do this for 2-3 times, and then it will turn off completely (external display has no VGA signal).
  
  Also reproduces with Kubuntu 15.10 (in Live mode).

Bug description:
