@kaihenfeng: I don't understand. Why should my case be a new bug?
Also, new info: I dist-upgraded to Ubuntu 18.10 Cosmic yesterday, and this bug remains. Wired LAN is not available after suspend-resume in release 18.10 as well. My wife uses an older HP dv6-3012he, and this bug occurs in her upgraded laptop too.
The good news is neither of us makes use of suspend, and if the system suspends for any reason, LAN is always restored with a system restart. This is a good-enough workaround for us. We prefer wired LAN to Wi-Fi for both security and performance reasons.
