           Summary: Glxgears crash with latest git (9.0)
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All

    Kernel driver in use: i915

Using latest drm git and xf86-video-intel from git.
My kernel is 3.5.3.

P.S: Using standard i915 (non gallium) driver, glxgears work well.
