I'm having this issue as well, with the 5.0.0-16-generic kernel on amd64 and an Intel I219-V NIC using the e1000e driver. I have a test case that can reproduce it somewhat reliably (involving a lot of concurrent back- and-forth chatter on my LAN).
I was able to reproduce it even after this command: ethtool -K enp0s31f6 gso off gro off tso off rx off tx off although anecdotally, disabling those features makes reproduction harder. After the original oops with backtrace (similar to the one posted above), the problem presents simply as: Jun 14 03:54:43 good-fortune systemd-networkd[7815]: enp0s31f6: Lost carrier Jun 14 03:54:43 good-fortune systemd-networkd[7815]: enp0s31f6: DHCP lease lost with no further backtraces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832101 Title: systemd-networkd: Lost carrier e1000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
