Description Bart Schuurmans 2015-02-06 14:45:56 UTC 
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.
Feb  6 15:25:55 lumen kernel: [257598.217866] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Feb  6 15:25:55 lumen kernel: [257598.217870] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Feb  6 15:25:55 lumen kernel: [257598.217874] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
