--- Comment #2 from Neil Roberts <neil at linux.intel.com> ---
I tested this on git master (f12302b89836a2) on SKL and it's also failing.
However I think it is due to the combination of glPolygonMode and
glVertexAttribDivisor rather than a general failure with glVertexAttribDivisor.
If I comment out the call to glPolygonMode then it works (albeit with filled

There is a piglit test called arb_instanced_arrays-instanced_arrays which tests
glVertexAttribDivisor and this does work on SKL.

This problem doesn't exist on HSW.
