I first noticed the problem while rebooting after a 5 day uptime…
The system boots, then sddm leads to a black screen under wayland. Only X11 works at this time …. Really frustrating !!!
journalctl output looks like this (after logging out from the session and switching from X11 to Wayland):

PS: Problem solved by downgrading the mesa package from 24.3.1-1 to 24.3.0 using sudo pacman -U https://archive.archlinux.org/packages/m/mesa/mesa-1%3A24.3.0-1-x86_64.pkg.tar.zst
An updated mesa version: mesa 1:24.3.1-2 also fixed the problem.
