Ah.. "st/mesa,gallium: add a workaround for Unigine Heaven 4.0 and Valley 1.0" is also included in mesa-10.3. So both Heaven 4.0 and Valley 1.0 should just work. The question is why ARB_sample_shading is causing GPU lockup on VERDE. Should I open a separate bug for this issue?
I can re-test VERDE when I get home.
I haven't investigated why the hw hangs, because it only happens if shader compilation fails and so none of the sample_shading shader stuff makes it to the driver. I think the likely cause is that Unigine attempted to do rendering with a shader that hasn't actually been compiled and things went wrong after that.
