TMU values are floating a lot, when cpu is under load

While capturing greyscale images, we can meassure a temperature value around 35.0 to 42.0 °C. The values changes a little, but are continous. When doing some calculations on the image and producing a high cpu load >80%, the tmu values start floating between 25.0 to 120.0 °C.

I can confirm, that the tmu-driver works correct, cause this does not happen in idle meassurement.


Can you reproduce these behaviour?
