GPU crash dump

Happened to me once before (with Chromium 34), and again today (Chromium
35.0.1916.114 Debian jessie/sid (270117)). I was reading a long webpage and
scrolling when the picture became stuck for a few seconds. Chromium did not
recover.

I am using Debian unstable with Linux 3.14.5 (self-built), libdrm-intel1
2.4.54-1, Xorg 1:7.7+7. If you need any further information, I'd be happy to
help.

dmesg:
[16139.620025] [drm] stuck on render ring
[16139.620028] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[16139.620029] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[16139.620030] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[16139.620030] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[16139.620031] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
