Created attachment 125712 [details] GPU crash dump from /sys/class/drm/card0/error During using the Google Chrome on Ubuntu 14.04/64 I often experience this error: Aug 12 03:28:56 * kernel: [105286.318002] [drm:ring_stuck] *ERROR* Kicking stuck semaphore on render ring Aug 12 03:28:56 * kernel: [105286.318007] [drm] GPU crash dump saved to /sys/class/drm/card0/error Aug 12 03:28:56 * kernel: [105286.318008] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. Aug 12 03:28:56 * kernel: [105286.318009] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel Aug 12 03:28:56 * kernel: [105286.318010] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. Aug 12 03:28:56 * kernel: [105286.318010] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. Doing as suggested: filing new bug. Mostly this appears after heavy Adobe/Pepper flash usage, but not always.
