这基本上是从 Ubuntu 20.04 升级到 20.10（英特尔 CPU）时 CPU 频率扩展中断
但是，我无权发表评论，因此有人建议我写一个新问题。请阅读原始问题以获取其他发帖者提供的更多信息。
从 kubuntu 20.10 升级到 kubuntu 21.04 后，我遇到了完全相同的问题：完全不同的 CPU 频率缩放行为，CPU 频率经常卡在 400 MHz。
使用 kubuntu 20.10，我新买的 AsusVivoBook S14 S435 配备 i7-1165G7，运行速度非常快。根据需要，频率会扩展到 >4 GHz，然后在 100% 使用所有 4 个内核（=8 个 CPU）时缓慢稳定在 >2.8 GHz，同时风扇速度显著增加。CPU 内核和“复合”温度约为 90°C。
使用 kubuntu 21.04 时，只能在很短的时间内扩展到 4 GHz 左右，然后降至 1 GHz 左右，甚至经常降至 400 MHz，同时温度保持在 <60°C 且 CPU 风扇保持低转速。有时节流会持续几秒钟，有时似乎完全停留在 400 MHz 几分钟甚至更长时间（我通常在卡住时重新启动）。
在这两种情况下，intel_pstate 似乎都处于活动状态，并且有两个调节器可供选择（powersafe 和 performance），但是当频率卡在较低值时，哪一个处于活动状态或我手动设置哪个频率都无关紧要。
我认为这一定是内核的差异：kubuntu 20.10 上的内核是 5.8，kubuntu 21.04 上的内核是 5.11。然而，事实并非如此：我已在 kubuntu 21.04 上尝试了内核 5.8 / 5.10 / 5.11 和 5.12，但行为没有改变。
我暂时将风扇调至最大转速，看看是否有什么变化。温度甚至更低，但仍然降速至 400 MHz。
我还排除了 BIOS 故障的可能性：就在我升级到 21.04 的时候，我也将 BIOS 从 3.01 升级到了 3.02。即使降级到 3.01 后，行为仍然相同。
最后，我从外部硬盘启动了 kubuntu 20.10，以排除任何实际的硬件问题——我的电脑又快速运行起来了。
我现在已经重新安装了 kubuntu 20.10，很高兴。但在某些时候我必须升级，因为对 20.10 的支持将在几个月后耗尽。但如果不知道是什么导致 CPU 节流，那真的不是一个选择。
即使所有相关温度都很低，有人知道什么原因会导致节流吗？

Doug Smythies 请求在发生节流时发布涡轮增压器信息。
我进行了三组读数：
- 使用 20.10
- 在发生节流之前使用 21.04
- 使用 21.04，同时将频率限制为 400 MHz
1+2 之间的差异 (20.10 --> 21.04)

两个安装中都缺少 /etc/thermald/thermal-conf.xml。当我手动启动 thermald 时，在 20.10 上它会抱怨缺少配置文件。
ps aux |grep thermald在 20.10 上没有给出结果（尚未测试 21.04）。
答案1
事实证明，这是 thermald 造成的差异。
thermald 安装在 kubuntu 20.10 和 21.04 上。但是在 20.10 上 thermald 无法启动。
当我在 21.04 上停止 thermald 时，节流就停止了。
sudo systemctl stop thermald
但是，此时一些设置已经更改，而 thermald 在停止时似乎无法恢复这些设置。所以我干脆完全删除了 thermald。
sudo apt remove thermald
重启后，21.04 的表现几乎与 20.10 相同。基本频率略低（1300 MHz 而不是 1800 MHz），但负载下的峰值和长期频率相同。
与卸载 thermald 相比，停用它应该具有相同的效果：
sudo systemctl disable thermald.service
