--- Comment #5 from Mark Janes <mark.a.janes at intel.com> ---
According to mesa engineers, mesa only emits 3DSTATE_VERTEX_ELEMENTS on-demand
right before 3DPRIMITIVE.

Chris has changed SNA to emit a dummy primitive between VertexElements in 
4acd4a7d3d2f41227022fa7581cfb85a0b124eae.

Yann, please do not assign any more xorg gpu hang bugs to Mesa unless they
reproduce with modesetting.

Svenne, switching to modesetting will probably resolve your issue.  For
example:

You could also update xf86-video-intel to anything after Chris's fix.
