--- Comment #5 from Henri Verbeet hverbeet@gmail.com 2010-11-08 13:44:03 CST --- This looks very similar to a known driver bug (although a backtrace wouldn't hurt). Specifically, this is probably the same as https://bugs.freedesktop.org/show_bug.cgi?id=27141, which was fixed by Mesa commit fef9b532cd1631cc53056b9eba4369d1310b88df back in July. That corresponds to Mesa 7.8.3 (unreleased) or 7.9 and later.
