The latter one takes effect when the core temperature is at least 85 degree celsius or higher So the current critical trip point doesn't make sense, because the thermal shutdown appears before the firmware has a chance to throttle the ARM core(s). Fix these unwanted shutdowns by increasing the critical trip point to a value which shouldn't be reached with working thermal throttling.
