            Bug ID: 64320
          Assignee: dri-devel@lists.freedesktop.org
           Summary: WebGL support in Chrome causes GPU lockup
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: marvin24@gmx.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

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.
