After Upgrade to 22.04. System does not boot into graphical mode without being connected to the network

[Jürgen Hemelt]

After long wait time many systemd services fail with a timeout. Connecting to a network via Ethernet does not make the boot continuing. When the network cable is connected before booting the boot process works fine.

Can you specify which systemd services are failing and timing out on boot? And can you provide some log output from those services?

[Jürgen Hemelt (jhemelt)]

Each time I boot it looks like the failing services are different. Currently I get timeout errors with

* systemd-timesyncd.service
* systemd-oomd.service

I attach the relevant output of journalctl --system below.

[Nick Rosbrook (enr0n)]

Thanks. I noticed the following kernel stack trace in that log:

[Jürgen Hemelt (jhemelt)]

Thanks for your help. Obviously this seems to be the reason for the bug. I blacklisted the ucsi_acpi module and the system boots correctly. Hopefully there will be a backport for the 5.15. kernel so that I can remove the blacklist. Otherwise I have to wait for an Ubuntu distro with 5.16. kernel.
Again thanks for your effort.
