Hi Colin, I ended up creating some scripts to reduce the maximum turbo boost of my CPU during heavy loads including the GPU. I just have a gnome key binding to flick between normal boost and GPU+reduced boost. I've managed to avoid these instabilities and things have been just fine.
> echo "60" | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct In addition to this, I installed some thermal pads on the CPU MOSFETs to bridge them thermally to the laptop aluminum cover (rather than just being air cooled). I'm not sure that this was necessary, but there were some examples of thermal imaging of them getting quite toasty above 80 degrees on the internet, and this seemed like a good solution with minimal cost. Anyway; the machine is on 21.04 now, so I keep it pretty up to date. I'm not sure if this continues to be a problem, but I am happy to reduce my CPU freq during GPU loads as I'm usually GPU bound anyways, it makes sense to keep things from getting too hot.

Disabling Turbo Boost prevents shutdown of the system. I'd expect thermald to performance throttle the CPU correctly to prevent it from a thermal overheat event.
