As the message says, this is not the real error. Somehow, the X.Org
server can't stand the flow of incoming events. Our Radeon driver may be
too old for your GPU generation and it may lack some optimizations.

If you feel like trying experimental stuff, here are some ideas:

    1. Newer X.Org-related ports are available in the xorg-dev
       Subversion repository. You could checkout the following branch:
       https://trillian.chruetertee.ch/svn/ports/branches/experimental/

       From that checkout, rebuild graphics/libdrm, graphics/libglapi,
       graphics/libGL and graphics/dri. I think that's enough.

    2. You could checkout my "kms-drm-update-38" Git branch:
       https://github.com/dumbbell/freebsd/tree/kms-drm-update-38

       In this checkout, you can just rebuild the kernel (a 11-CURRENT
       kernel). Keep your world untouched, so that you can come back
       easily to plain 10.0-RELEASE.
