This is the second time in less than a week that I get this GPU Hang since I updated to Ubuntu 15.10 with a Linux kernel 4.2. Fortunately, the GPU reset recovers without any system reboot needed. This happened while just surfing on the net with firefox. uname: Linux 4.2.0-17-generic #21-Ubuntu SMP x86_64 dmesg extract: [70280.804135] [drm] stuck on render ring [70280.805158] [drm] GPU HANG: ecode 3:0:0x717fffc1, in Xorg [992], reason: Ring hung, action: reset [70280.805161] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
