Can you please bisect this? Which one is the bad commit?
No need to bisect, the error message was introduced by Oscar in commit 38cc46d73ed99dd7002f1406002e52d7975d16cc Author: Oscar Mateo <oscar.mateo@intel.com> Date: Mon Jun 16 16:10:59 2014 +0100 drm/i915/bdw: Ack interrupts before handling them (GEN8) And for those reason bit 23 of master ctl is set and the SDE IIR is 0.

Hi It seems you're booting with eDP+HDMI. I can't reproduce this with eDP+HDMI or just eDP. Can you please confirm whether this only happens when you boot with DP (or DP+something) attached? Thanks, Paulo

Created attachment 104474 [details] dmesg(14bf99) It doesn't happen on latest -queued and -nightly kernel.I guess someone fixed it.

Verified on latest -nightly(723dbbfb6ce02b5662c0c4cac9be3bcdfbb11d35) [root@x-bdw01 ~]# dmesg -r | egrep "<[1-3]>" |grep drm [root@x-bdw01 ~]#

Comment on attachment 116126 [details] dmesg output, post event This happens on a new NUC, with CPU0: Intel(R) Core(TM) i7-5557U CPU @ 3.10GHz (fam: 06, model: 3d, stepping: 04) I'm running a 4K display off the miniDP port. It happens almost every single time I walk away from the computer within 10-15 minutes.

Created attachment 118836 [details] The master control interrupt lied kernel output on a Lenovo X1 Carbon (3rd gen) connected to a lenovo onelink pro dock
(In reply to Kim Carlsen from comment #14) > Created attachment 118836 [details] > The master control interrupt lied > > kernel output on a > Lenovo X1 Carbon (3rd gen) connected to a lenovo onelink pro dock Outputting 2560x1440@60 works fine, outputting 3840x2160@60 produces no picture on external monitor. When removing the onelink prodock and connecting the dp cable directly to the laptop then all resolutions works (3840x2160@60). Whenever running xrandr it adds 36 lines to kernel log of 'The master control interrupt lied'
When 4k resolution is working, these error message is still present in kernel.log. Maybe resolution issue is unrelated to IRQ issue
