Comment 49 for bug 1861936

@hui.wang - yes, I have seen this a few times in Focal since upgrading about a month ago. I didn't look at the logs closely, but the message that appears repeatedly after the interface fails is "eth0: kevent 0 may have been dropped" I think, and bug #1647397 may be related/identical.

User from that bug ascribes the cause to the use of bridge, and this is my case. @Matt, are you also running the interface in a bridge?
