Comment 0 for bug 1956821

After upgrading from kernel 5.13.0-22-generic to 5.13.0-23-generic, the system cannot be powered down or rebooted, just hangs indefinitely.

A screenshot with the final screen is shown here:

Is there anything I can do to provide more information and debug this further?

My system information:
Description: Ubuntu 21.10
Release: 21.10
