I tried without network:
(1) standard login after boot, with a monitor running on tty1. No loops.
(2) disabling NetworkManager, and disconnecting from the wired network; rebooted and logged in, with a monitor running on tty1. No loops.
So I cannot repeat the issue. I depend on you to get a backtrace with E-D-S symbols so that we can dig further on this.
