And here's some proposed text. I assume this would be applicable to the release notes from 20.04->22.04
= Known Issues = == Network Interface Names == Ubuntu generates [predictable interface names](https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/) by default. These names are influenced by the information exposed by kernel drivers, and this can therefore vary from kernel release to kernel release. For example, Mellanox Connect-X 5 adapters are known to be assigned names such as enp1s0f0 with Linux 5.4, but be assigned a name like enp1s0f0np1 in Linux >= 5.8 (bug 1940860). If you find your system is impacted by such a name change after a kernel upgrade, you will need to update your network configuration files. If you would like to retain the same network interface names when switching between kernels, [netplan](https://netplan.io/reference/) provides a "set-name" field you can apply to your interface configuration. When set, this will cause Ubuntu to use the defined name instead of the default. ** Changed in: systemd (Ubuntu) Status: New => Invalid ** Changed in: linux (Ubuntu) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940860 Title: Mellanox NIC interface names change between 5.4 and 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/subiquity/+bug/1940860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
