There's some bits in the thermal drivers I've been looking into recently where I have certain machines where the thermal chip is left in automatic mode but also the system attempts to drive it in manual mode, which causes things like the fans jerking on and off and spurious 103.0C readings on the temperature probe the chip is internally sampling. I half wonder if there's a similar issue causing us to accidentally crash the chip or something.
