Comment 25 for bug 1973434

I've been having very similar issues on a lenovo legion laptop, disabling intel_iommu helped but doing so wouldn't give me results as smooth as windows/manjaro.

One thing that i noticed is that if my cpu (i7 10750h) gets stressed enough and reach high temperatures Ubuntu will throttle all cores to 800mhz.

Disabling thermald with `sudo systemctl stop thermald && sudo systemctl disable thermald && sudo shutdown -r now` apparently fixed the issue for my laptop. I even removed the `intel_iommu=off` workaround from /etc/default/grub since it seems it's no longer necessary and my system is still super smooth so far

I've been running multiple cpu-heavy docker images from work and the max temperature I recorded in any core was 95C, for reference according to sensors i7-10750h considers any temp up to 100C as high, only above that is that it becomes critical.

Since those images stresses my system a lot (even on manjaro) it's safe to say that even after disabling thermald cpu cooling is still working, otherwise my laptop would've probably shut off by this point
