Bug#810120: linux-image-3.16.0-4-amd64: i915 drm, dualscreen, FIFO underrun, kernel call trace

[Hans Meiser <x201userbugreport@gmail.com>]

I recently installed a backported linux image:
> linux-image-4.3.0-0.bpo.1-686-pae

with this the crashes do no occure

Only things which occure are those FIFO underruns:
> [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun
they don't seem fatal.

Regards.
