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.</pre>
