GPU crash dump

Hi there,
I suddenly seem to have strange graphics bugs, for example sometimes missing letters in the text of web pages. Attached is the corresponding GPU crash dump.

I found this in my logs:
Jun 15 17:59:08 eeyore kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
Jun 15 17:59:08 eeyore kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Jun 15 17:59:08 eeyore kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Jun 15 17:59:08 eeyore kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Jun 15 17:59:08 eeyore kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
Jun 15 17:59:08 eeyore kernel: [drm] stuck on blitter ring
Jun 15 17:59:08 eeyore kernel: [drm] stuck on render ring

Is my hardware dying or is this a bug?
