A restart, and,  I still have the same issue: No improvement.

  dmesg | grep drm:intel

  [    1.441536] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
  [    1.441575] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

  Returned back (https://bugzilla.kernel.org/show_bug.cgi?id=79261). It
  seamed to be fixed up-stream but not for all.

  Effects on my DELL Precision E6530: without notice it switches from
  nouveau to nvidia. Switching back to nouveau it hangs (need restart)
  and OK.

  Using optimus: 
  00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
  01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [NVS 5200M] (rev ff)

  I'll try to use the upstream kernels and inform ...
