Hello all, If i shutdown one of my container (gentoo) from PVE, after timeout the container crashes. If i shutdown it inside the CT it works (acpi is on). But on both situations i get this strange error, all 5 seconds. For about 10 Minutes. Code: Message from syslogd@pvehost at Apr 3 01:45:25 ... kernel:[210333.954073] unregister_netdevice: waiting for lo to become free. Usage count = 3 Here is my configuration.

This was an old kernel bug (before version 4.13 I think), but there are apparently other cases where this can happen. Can you post `pveversion -v`? Also maybe describe what's running on this container exactly? I'm seeing some DVB stuff. Does this happen with other containers at all?

I can't reproduce this problem with a regular Gentoo container. Also tried with the mount entry from your config, didn't make any difference. Your package versions and the kernel also looks normal and up to date. Must be something with whatever is running in the container? Can you describe a bit more?
Yes you are right. It is depending on the dvbcard. If i remove the two special configlines, the message is gone away.
