Also observing this in 20.04.2 (kernel 5.4.0-70). I will try swapping out physical transceivers on both ends of the link and a new switch port...
Of particular interest to me, netplan does not appear to re-run when this happens. I have a device renaming rule that matches on name, sets IP, and sets name. This device never comes back up unless I manually run netplan apply (which is always successful, but obvs. untenable). The root device (eno2) is not even listed in `ip link` output during the incident. Please advise what logging/information I can provide to help track down culprit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775131 Title: Ubuntu 18.04 networking issue (connection drops after approx. 15 minutes) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
