the i915 driver is still broken in 3.16-rc2. Resume from ram crashes the
X server.

        drm/i915: disable rings before HW status page setup
    
    we reordered stopping the rings to do so before we set the HWS register.
    However, there is an extra workaround for g45 to reset the rings twice,
    and for consistency we should apply that workaround before setting the
    HWS to be sure that the rings are truly stopped.
