For the record, the bug is still there. The following is taken from a post-suspend dmesg command. Impossible to get my USB-C to ethernet adapter to work until I reboot. This happens quite often. I have to reboot from time to time in order to get network back. You can imagine how frustrating it is when you find yourself being afraid of disconnecting or suspending your laptop to avoid having to restart all your apps to get back in current context of your work. I am using the latest 20.04.1.
