full dmesg with hang at the end

Software: linux 3.8-rc2, the problem also occured in rc1. In 3.7 it does NOT
hang.
mesa/xf86-video-intel are the latest from git master, I'm also using sna
Hardware: i7 3632qm

Unfortunately I have only been able to trigger this bug with flash 11.5 but
fortunately it always happens immediately so it's easy to reproduce.

Steps:
Use google chrome / chromium with pepper flash
Watch a flash video (e.g. from youtube) / try to put it on fullscreen

Without compositing: As soon as the video starts the hang occurs
With compositing (kwin 4.10 beta, opengl): The video plays fine, but as soon as
I put it on fullscreen the hang occurs.

Maybe I'll write this snippet from dmesg directly here so it's easier to find
with google (I have not found that exact problem):

[ 1424.837260] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU
hung
[ 1424.837270] [drm] capturing error event; look for more information in
/debug/dri/0/i915_error_state
[ 1424.842657] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring

The rest is hopefully clear from the attached files.
