Ex-gentoo user here. In one of my ancient laptops, amd64 from 2006 maybe, the default kernel that came with the bootstrap Gentoo did not handle well throttling CPU speed. It was always by default to the maximum available and, thus, after some time the laptop would switch off itself because of excess heat.
The only solution I found was to compile another kernel with the correct extensions loaded and put a big fan under the laptop during that process.
Anyway, the situation was really funny for my coworkers but I learnt a lot of things thanks to Gentoo.
- nubinetwork 4y agoWas it an intel CPU? My laptop also had issues with throttling, but it turns out that turbo boost was on, and the BIOS had no way to turn it off. I wound up writing a cronjob that does "echo 1 > no_turbo" every minute... although it only really needs to be done once per boot, or every time you plug/unplug.
- patatita 4y agoNo, it was a AMD. I didn't found any way of solving it through the BIOS.
- nubinetwork 4y agoPretty sure there is an AMD no_turbo equivalent, but I don't know what it is off-hand... My 2950x had a BIOS toggle so it's locked to the base frequency.
