--- Comment #1 from lu hua <huax.lu at intel.com> ---
Test on drm-intel-nightly kernel(79e44bfa100) and latest Mesa master branch.
Run "bin/shader_runner
generated_tests/spec/glsl-1.30/execution/built-in-functions/vs-op-lshift-ivec2-uvec2.shader_test
-auto" 50 cycles, it doesn't have this issue. but run following cases still
have GPU hang.

Output:
 bin/shader_runner
/home/GFX/Test/Piglit/piglit/generated_tests/spec/glsl-1.30/execution/built-in-functions/vs-op-mod-ivec2-int.shader_test
