--- Comment #4 from Kenneth Graunke <kenneth at whitecape.org> ---
This looks really strange.  These look like Mesa (3D driver) batchbuffers
(based on the binding/sampler/constant/unit state sequences), but the sequence
before the hanging flush is:

1. VS related state.
2. GS disable state.
3. PS related state.
4. 3DSTATE_VERTEX_BUFFERS
5. 3DPRIMITIVE.

But, as far as I can tell, Mesa /always/ emits 3DSTATE_VERTEX_ELEMENTS after
3DSTATE_VERTEX_BUFFERS.  It's always done in the same function, directly one
after the next.  So, I'm not sure what to make of this.

What version of Mesa are you using?  It's clearly not 10.1, but I'm not sure
how far back it is.
