Just a PSA I ran into an issue with my Lenovo Slim Pro X (14ARH7) took me a while to figure it out. There is a regression in the 6.4.6 kernel that breaks the keyboard on many Lenovo laptops. Here is a link to the bug report
https://bugzilla.kernel.org/show_bug.cgi?id=217718
So either pin you kernel to 6.4.5 or use the the LTS kernel. I went the LTS kernel route until this is fixed.
I had the same thought, I though maybe I was missing some dracut modules because I had switched to dracut from mkinitcpio. I have to stop doing more than one thing at a time because I updated my kernel while switching to dracut , so it sent me on a wild goose chase. Then I started thinking the keyboard was broke, bummed me out until I found that bug report.
This is the thing about Linux, we are always changing things so it’s hard to know sometimes what the issue is :)
