Comment 22 for bug 1987829

I'm experiencing this problem on an LG 14ZD90Q with Ubuntu 22.10, latest packages and kernel from the default repos. Mostly the problem occurs when the charger is plugged in, but today it also happened for a while when I had no USB-C devices connected. (I was using a couple of USB-A devices, a keyboard and mouse.) I found a mitigation: disable Intel Turbo Boost, per https://www.tautvidas.com/blog/2011/04/disabling-intel-turbo-boost/ (tl;dr: echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo as root.) It's not a fix, the CPU still keeps maxing out for no reason, but at least it doesn't overheat or max out the fan anymore. Might be useful while we wait for a kernel fix that stops this triggering in the first place.
