Created attachment 126536 [details] DRM Error DRM Error I have a Broadwell-U device, XPS-13-9343 which has a i7-5500U with Intel HD Graphics 5500 (a Gen8 Graphics). It occurs random gpu hang since kernel 4.x. These bugs are not likely to reproduceble, some times it got a gpu reset and in other case the device just get frozen. I attached a DRM ERROR and a Dmesg when a gpu hang happened and it recoverd after chip reset.
