On a ThinkPad T480 running Fedora 42, I've discovered that more or less every five minutes, systemd has been writing Reached target shutdown.target - Shutdown. to journalctl. (See example text below, which is part of the output of journalctl | grep shutdown.) But the system does not shut down; this has occurred for every boot currently recorded in journalctl (which for me is the last 33 boots).
Not sure if it's relevant, but I also see some line containing dracut-shutdown.service - Restore /run/initramfs on shutdown when I grep for "shutdown".
Any help is appreciated. What should I start looking into to diagnose this issue?
