From your log file it seems you have a "phong_nonbasic_8659449695711977334" material. Not sure what that is? It does build the material, but you see that the CL_OUT_OF_RESOURCES message happens just as it's about to optimise the material code for that material.
Oren Nayar materials definitely works using GPU, so I doubt that's the actual problem here. Try the Reinhard option and see if the render remains black.
That material was a phong with a shader, and you're right, disabling that made the error disappera.
I've now disabled all shaders, yet the image remains pitch black, even with Reinhard tone mapping.
