Description of problem: dmesg and /var/log/messages are flooded by error: [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)! Version-Release number of selected component (if applicable): 4.3.3-300.fc23.x86_64 How reproducible: always Steps to Reproduce: 1. boot 2. dmesg -r | egrep "<[1-3]>" |grep drm 3. Actual results: see multiple occurrences of the error string Expected results: no error Additional info: NUC 5i5, eDP connected monitor. The error was present even before the last kernel update (also having only hdmi connected monitor), but after last update it really floods the logs
I've already committed a fix for this in the Fedora git tree. It will be fixed with the next build.
Just for completeness since I had that link here: https://bugs.freedesktop.org/show_bug.cgi?id=92084 Mentions kernel-fix: commit 2dfb0b816d224379efc534764388745c474abeb4 Author: Jani Nikula <jani.nikula> Date: Thu Jan 7 10:29:10 2016 +0200 drm/i915: shut up gen8+ SDE irq dmesg noise, again
