Created attachment 130757 [details] dmesg output This happened on a ThinkPad T460p with Intel HD 530and the following software versions: * stock Kernel 4.10.8 * Mesa 13.0.6 * x11-intel drivers from git from 20170313 * libdrm 2.4.75 * xorg-server 1.19.2 I had problems after docking the laptop in to the docking station, which was attached to two screens (one through DP, one through HDMI): the external screens stayed black and the laptop was frozen. After undocking it became responsive again. Problem was reproducible and appeared also after hibernating and waking up the laptop. Please find dmesg output attached, which contains a lot of drm related error messages. $ cat /sys/class/drm/card0/error no error state collected No relevant messages in Xorg.log
Please try current drm-tip branch from https://cgit.freedesktop.org/drm/drm-tip
Robert - can you help us here and try reproduce the problem with the latest drm-tip?
I haven't been able to reproduce the problem with either drm-tip nor vanilla 4.11. I'll let you know if I can reproduce it again.
