i had cachyOS installed for a couple of months but was plagued with random system freezes (only hard reset possible, no leads in journalctl). i tracked it down to an issue with the combination of wayland, KDE plasma and the kernel or at least that’s what i could gather from web searches. i had at least one of those freezes per week, often more.
i am now on kubuntu which basically has the same combination of things (wayland and KDE) that should cause the problem but it has been running fine for three weeks, no freezes. so something with the cachy kernel didn’t agree with my system.
i was now told i could use the arch kernel on cachyOS, which was news to me. i tried switching to the cachy LTS kernel but the issue persisted. i now wonder how does the compatibility of the linux kernel work? is it compatible because it is both arch linux? or would the kubuntu kernel also work on cachyOS?
It’s hard to say for sure what’s causing the issue, but it’s definitely possible that it’s kernel related. I’ve never used cachyOS, but when i was still using Arch i’ve had issues with newer kernels multiple times. Switching to the LTS kernel would usually fix the problem though. I’m actually facing a weird issue myself right now on GNU Guix, where my pc has randomly rebooted itself multiple times over the past few weeks. My first thought was the kernel since Guix is also rolling release, but i haven’t tried the LTS kernel yet because the nonguix substitute servers are having issues, so i would have to wait for it to compile lol.
Oh btw regarding your question, i don’t know if cachy offers the regular arch kernel in its repos as well, but generally speaking kernels should be pretty compatible regardless of distro. You can also install the cachy kernel on NixOS for example.
thank you!
