<pre>A Skylake machine with BIOS upgraded now gets a distorted display after resume
from suspend, and the logs show:
[ 52.754334] [drm:gen8_irq_handler [i915]] *ERROR* Fault errors on pipe A
[ 52.754334] : 0x00000000

[ 52.756626] : 0x00000000
repeated ad infinitum.
happens with current drm-intel-nightly too.
Apparently the new BIOS has "Intel RC code 1.4.0", whatever that means.. Old
working one had 1.3.0.</pre>
