Created attachment 118711 [details] GPU kern warning before actual system hand Intel i5-6600K / Z170 system with latest git drm-linux, mesa and xorg. Some graphics operations can hang system if there has been GPU hang before. Attached is an example of recovered GPU hang, but the hard hang is fast enough not to leave trace even in serial port. Mika Kuoppala knows about this issue.
