Nobuto will see if they can do a reduced test in the environment also for 21.04, but they surely can't do a full redeployment. Therefore I prepare for the case that this won't happen... Since the patch is already part of 19.11.10+ (queued for 19.11.11) and just prefetched here the same rules as for the MRE apply. That was/is covered in bug 1940913. Those tests now all completed and are good. While I'd appreciate if someone could do and add test results of any kind of complexity in an environment with those cables - what we have is already sufficient to call it verified by the MRE exception rule. ** Tags removed: verification-needed-hirsute ** Tags added: verification-done-hirsute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940957 Title: DPDK ports get disabled after Open vSwitch restart with Intel XXV710(i40e) and 25G AOC cables To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpdk/+bug/1940957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
