The gsraytrace demo from mesademos 8.2 fails with the following output on mesa-11.0.0-rc2 on Intel Sandybridge:
$ LD_LIBRARY_PATH=/usr/local/lib /usr/lib64/mesa/gsraytrace GL_RENDERER = Mesa DRI Intel(R) Sandybridge Mobile ESC = exit demo left mouse + drag = rotate camera intel_do_flush_locked failed: Input/output error intel_do_flush_locked failed: Input/output error
No special input is required, the demo crashes right away. The same also happens with the system mesa which is at version 10.6.3.
