We can fix the G965 render state mem allocation, but I saw the same crash
as in exa accel case when rotation, current workaround is to disable DRI.
I'm still debugging on this, it looks like DRI smashing the ring buffer somehow.
And on 915 if I drag the glxgears window, it will also crash server...
