Created attachment 224101 [details] Kernel panic screen Since I use 4.6.x kernels, my laptop is freezing during boot time, showing sometimes a dark screen or a kernel panic message (two leds are always flashing : Caps lock and Num lock). With 4.5.x kernels and previous one, no problem. When I tried 4.7.0-rc7 kernel, the problem disappeared.
