Public bug reported:

After upgrading my 22.04 host to 6.5.0.35 HWE kernel, the system stopped
booting, seeming going into multiple wait/timeout sequences within
systemd.

The issue is similar to the thread reported at
https://lore.kernel.org/lkml/zpzqvxuw+dbkl...@torres.zugschlus.de/T/

Removing the grub parameter console=ttyS0,115200n8 from the grub config
resolves the issue, but cancels out my OOB access to the OS.

The issue also reproduces with 6.5.0-41.

Additional details:

- Ubuntu 22.04
