That's a different issue, which also reproduces upstream. I think it has something to do with an errata for this hardware. Does the controller probe successfully from inside the guest? We should have a new bug opened to track it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1596635 Title: KVM system crashes after starting guest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1596635/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
