<pre>After some narrowing down I hacked the driver to use CCS_E only for three
surfaces of size 1920:1080. None of them is mipmapped or arrayed. Two of them
are rendered and sampled as pair. Disable CCS_E even for one these and I don't
seem to get the gpu hang anymore. But even with these three I get roughly one
run out of four runs without the hang. So I don't have anything conclusive yet.
Still trying to narrow this down.</pre>
