Reading logs between a successful run on x86 and a failed run on s390x, it would appear that stp never sees the topology change on br0 as p2 is removed - this log message is missing from the s390x logs:
br0: detected topology change. so I suspect the fdb cache ends up hitting some sort of age timeout before it gets flushed, rather than being activity flushed as a result of the topology change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722799 Title: 2.8.0: test failure under s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1722799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
