P.S. /var/log/syslog lists lines these before I upgraded to Debian-13.So these lines where written when I was running Debian-12 with a 6.12.x kernel, which I compiled myself.
systemd-timesyncd.service: Watchdog timeout (limit 3min)! systemd-udevd.service: Watchdog timeout (limit 3min)! systemd-journald.service: Watchdog timeout (limit 3min)! But systemd-logind startet appearing only after upgrading to Debian-13. So I guess the underlying issue existed for a longer time.At the moment I think, that it's probably a s2idle kernel issue that existed for a longer time. So let's see how the previously mentioned upstream kernel issue turns out.
