--- Comment #9 from Sven Arvidsson sa@whiz.se 2011-06-03 13:54:28 PDT --- I noticed that a few piglit tests causes GPU hang/resets when run with MESA_GLSL=nopt. Is this to be expected or is it worth to file bugs?
The failing tests are glsl-fs-atan-2, glsl-fs-lots-of-tex, glsl-orangebook-ch06-bump and possibly others. They run without problems if nopt isn't used.
