Disable CPU migrations (Linux 5.1.13 & newer) with systemd-boot on Catchy OS:

*Note: you cant edit the "/boot/loader/entries/linux-cachyos.conf" firectly since your custom changes will be lost when running pacman update. To edit the cmdline sucessfully with systemd-boot edit this line with nano:

sudo nano /etc/sdboot-manage.conf

Add this to the LINUX_OPTIONS line near the top of the file:
mitigations=off

Save by Ctrl+X then Y.

Then run un this command to apply to the loader file:

sudo sdboot-manage gen

Then reboot!
