--- Comment #15 from Dieter Nützel <Dieter at nuetzel-hh.de> ---
Update,

this one is NOT solved with current Mesa git.

For EG+ (Bug 91865) this is _fixed_ by 'accident' in Mesa git since:

commit 2239f3eaff5c72c4cb1d4a5be97feb4af3d08d25
Author: Dave Airlie <airlied at redhat.com>

    r600/shader: emit tessellation factors to GDS at end of TCS.

    When we are finished the shader, we read back all the tess factors
    from LDS and write them to special global memory storage using
    GDS instructions.

    This also handles adding NOP when GDS or ENDLOOP end the TCS.

    Signed-off-by: Dave Airlie <airlied at redhat.com>

Dave and Marek any hints which could point in the right direction?
What is different in this case between R600/R700 and EG+ (NI/Turks in my case)
and what should I try next.
