--- Comment #3 from Laurent Bonnaud <L.Bonnaud at laposte.net> ---
Please note that during boot I see the following error message:

[    2.455186] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun
[    2.455228] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR*
uncleared pch fifo underrun on pch transcoder A                                 
[    2.455252] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH
transcoder A FIFO underrun

I never bothered about it previously because it does not prevent the system
from booting and from displaying graphics.

Do you think it is related to my main graphic problem?
