The 36xx > values are behaving AFAIK. Just disabling the bandgap doesn't seem to be enough. I also tried disabling just the bandgap and thermal_zones, but that is also isn't enough. However, *just* disabling cpu_thermal also isn't enough. Disabling both cpu_thermal and bandgap is enough to stop the oopses [1]. So it sounds like there might potentially be some problems in cpu_thermal as well then?
