Public bug reported: Recent kernels are using predictable naming for network interfaces, so the network stack is more tied to PCI naming. This can be a problem in hotplug scenarios, because PCI addresses will change if devices are removed and then re-added. This situation seems unusual, but it can happen if a user wants to replace a NIC without rebooting the machine, for example.
The patch attached here should deal with this situation, since it makes PHB/domain number fixed based on device-tree properties. The problem can be reproduced by removing and re-adding a PCI network adapter, so its address will change and, per predictable naming scheme, so is the interface name. ** Affects: ubuntu Importance: Undecided Assignee: Taco Screen team (taco-screen-team) Status: New ** Tags: architecture-ppc64le bugnameltc-139480 severity-medium targetmilestone-inin1604 ** Tags added: architecture-ppc64le bugnameltc-139480 severity-medium targetmilestone-inin1604 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1560514 Title: Predictable naming mechanism is leading to issues in DLPAR operations of NICs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1560514/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
