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.
Any idea why this bump mapping shader on a Phong material does not work on GPU/OpenCL:
<shader><![CDATA[def eval() real :
fbm(getTexCoords(0) * 6.7 , 3 ) * 0.0002]]></shader>
EDIT: this shader *does work* in CPU mode
