The Debian 3.16.0 kernel does not emit the error, but I have not attempted a
bisection.
The warning was added by:
38cc46d drm/i915/bdw: Ack interrupts before handling them (GEN8)
2014-06-18 (1 year, 4 months ago), Oscar Mateo <oscar.mateo@intel.com>
Follows: v3.15-rc8
Preceedes: 3.17-rc1
This is not present in v3.16, so perhaps not present in the Debian kernel and
this is not a regression, but just reporting the condition as intended.

But we don't start hitting the warning right away with that commit, do
we? There's a bug about this with a bisected bad commit [1], please
let's track this there.
Thanks,
Jani.

I get the exact same dmesg too with the 4.3.0-rc5 on a i5-5250U NUC
using HDMI. The rest is a standard Debian Jessie.
