Description:
I have a feeling someone in the arch community can't live and breathe properly if they don't screw up the rolling kernel at least once a week or per sub-version! From kernel 6.0.2 until 6.2.6 everything was perfect. But with the update to version 6.2.7 opening even the simplest text editor (nano) became a challenge (as if my computer has hardware from 2001), let alone GUI applications like calculator or gedit, SSDs and HDDs all "think" like crazy, the CPU was constantly at at least 80% load (surprisingly enough the video card was calm), the X session crashed a few times and restarting X not only didn't do any good but actually made things worse, so I had to reboot the whole system. And that reboot would solve the problems for about 5 minutes, after which everything described started happening again. And ALL that was happening in idle state - meaning there was no game running, only Firefox, PCManFM and a few autostarting processes, such as conky.

I solved the problem by installing the LTS kernel along with nvidia-lts and I'm seriously considering to get rid of the rolling kernel and keeping only the LTS kernel.

Additional info:
* package version: kernel 6.2.7
* config and/or log files etc. - no. Unfortunately the X session crashes weren't printed in ~/.xsession. This file was last changed on 27 Aug 2022 which means the problem wasn't reflected in it.

Steps to reproduce:
I wish I knew. I simply updated the kernel along with a few python packages and after the reboot the described things started happening.
