--- Comment #9 from Shuhao <shuhao at shuhaowu.com> ---
Does anyone else here experience CPU/GPU performance drops when they experience
these hangs? 

I think these are due to overheating but I can't be sure as the clock freq of
the CPU is not being limited. Previously, that happened when I hit 95C, where
as these slow down happens when my core hits roughly 86C. 

Laptop is a Thinkpad T420. Critical temp is 100C. It's been documented that
these laptops will hit these temperature after computationally intensive tasks
such as games.
