Public bug reported:

I use Samsung NP350V5X-S0IN notebook with intel and AMD graphics with
Ubuntu 16.04 LTS with Mate 16,04. Very recently i had updated kernel due
to suspend and wakeup issued and it is cleared now. But however im
getting an error on bootload as follows:

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

I tried few methods like customising LSB-RELEASE and rebooting with the following file contents:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=15.04
DISTRIB_CODENAME=wiley
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"
as found in one https://allanbogh.com/2016/01/05/ubuntu-16-04-installing-the-intel-graphics-drivers-using-the-intel-graphics-installer-for-linux/

It didn't workout for the time being. Is there anything else as
required?
