The motherboard in question is the MSI x470 Gaming Plus Max. The original BIOS had to be flashed to version 7B79vH4.
On a side note, I ran into the very same issue with an ASUS x470 Prime Pro. Same remedy: a BIOS flash (I used version 5406). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1865289 Title: ubuntu 19.10: libvirt hangs host shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1865289/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
