--- Comment #10 from Wang Zhenyu <zhenyu.z.wang at intel.com> ---
I'm not sure, as that one seems to be vulkan issue.

For this one, if you download my trace file, it actually hangs at call 233679,
which is a compute shader program dispatch. Although this program has been
dispatched for several times, maybe somehow uniform or shader storage buffer
input has caused trouble in this shader, as you can see that it has loop
internal. 

And another thing worth check is if there's any overflow of ssbo write. Is
there anyway to check that from i965 backend?
