<pre>Kernel 4.8.5
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
Model name: Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz
After kexec using xrandr to turn off HDMI2 (DVI output connected via HDMI
cable) causes the kernel to apparently crash.. unfortunately I dont even get
anything in pstore so I dont have more info.
Pretty sure this worked for me in 4.7.x
