--- Comment #10 from Thomas Rohloff v10lator@myway.de --- I did go back till http://cgit.freedesktop.org/mesa/mesa/commit/?id=6c99f2101fbd3edb7d5899c44ca... and the bug is still there (not the crashes directly, at least I couldn't trigger them, but the error messages) so either this bug is really old or it's not a mesa bug (or, but that would be really bad: It damaged the hardware).
