Yes, I suppose this could be a thermal problem. Or it could be something else entirely. We do support CPU frequency scaling on Tegra X2, so what you could do is keep the Denver CPUs enabled, but set the powersave CPU frequency governor. That way it should use all the CPUs but at a lower clock rate, which should also be able to avoid any thermal issues. This could help determine whether or not the problem is thermal or something else. Also adding Mikko on Cc who wrote the Tegra186 driver, maybe he's aware of any issues. Thierry
