Ok, if I apply the whole suggested patch but the following, it hangs:
@@ -4152,14 +4152,14 @@ int ni_dpm_init(struct radeon_device *rdev)
     }
     ni_pi->mclk_rtt_mode_threshold = eg_pi->mclk_edc_wr_enable_threshold;

     rv770_get_engine_memory_ss(rdev);

I'll try to play with that a bit and I'll come back. I also still have to give
you the module_index.
