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.

I did a google search and didn't find any relevant hits for this error. So I reported it here. I should ahve searched the bug list also. I'll do that next time.

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.
