I've managed to test bionic as well. It is pretty much same as xenial. That means while the source code is broken, in a sense that the compiler is allowed to generate broken code, the generated code does not exhibit the issue in question. As with xenial I do see intermittent connection problems with iperf3, but the recv queue does not get stuck for good (like in focal, because of the lost interrupt). The presumably fixes the code source I can not see any positive or negative impact with regards to the intermittent and recoverable connectivity problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894942 Title: [UBUNTU 20.04] Lost virtio host --> guest notifications cause devices to cease normal operation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1894942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
