<pre>googles chrome browser causes gpu lockup on my RS880 while showing
maps.google.com and enabling WebGL renderer. For this to work, you need to
manually override gpu blacklist with "--enable-webgl --ignore-gpu-blacklist" on
the command prompt. Check with about:gpu that hw accel is enabled.
Mesa/LLVM/drm/ddx is from today (May 7th) and kernel is 3.9.
