 kernel:reboot: HARDWARE PROTECTION shutdown (Temperature too high)

I am running it headless over OTG/USB1.

what kernel? 6.1.y vendor?

Odd as I was just testing a 6.6.y build and ran into the same issue. Which is why I'm asking.

Anyway... Not sure what ur doing headless, but It looks to me you over extended and it tripped and shutdown to save its self. Put some heat sinks on it and adjust the scaling.

governor -h
CPU frequency scaling
Usage: 

    -c  Conservative
    -o  Ondemand
    -p  Performance
    -s  Schedutil

    -r  Run
    -u  Update

6.1 kernel, doing nothing fancy actually. Not using the GPU for sure. It has a full on heatsink and 2 thick thermal pads, might just put a thermal pad on the GPU as well probably.

This kernel is hackery and mainline still has a ways to go.
