Cool.  Glad that fixes it.  I've merged that patch to master:

    anv/skylake: disable ForceThreadDispatchEnable

    On Skylake enabling of ForceThreadDispatchEnable causes gpu-hang.

    -v2: enabling of  ForceThreadDispatchEnable is only for gen8, for
         gen9 and higher reverted enabling of PixelShaderHasUAV.

    -v3 (Jason Ekstrand): Rework the comments a bit.
