dmesg with drm.debug=14
Since new install of my Linux System and using a 4.4+ Kernel (before 3.19) I'm
getting kernel exceptions every time I disconnect my via HDMI connected
Monitor.
Steps:
- booting to desktop without problems
- disconnect HDMI
- eDP is showing desktop for ~2 seconds
- eDP turns black, no keyboard inputs, the rest keeps running
No difference if HDMI connected while/after boot, I tried different 4.4+ Kernel
Versions from Ubuntu to Mainline, every time nearly the same output.
