I was playing video using Kodi/xmbc when the video output froze on a single frame, but the audio kept playing. After killing the Kodi process, I got this error in /var/log/syslog: Feb 6 15:25:55 lumen kernel: [257598.216235] [drm] stuck on render ring Feb 6 15:25:55 lumen kernel: [257598.217853] [drm] GPU HANG: ecode 0:0x87d3bffa, reason: Ring hung, action: reset Feb 6 15:25:55 lumen kernel: [257598.217861] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
