I found something interesting. The original dump above was reproduced with kernel 4.4.0-94-generic in the hypervisor. It is very hard to reproduce this issue on the following hypervisor (I just reproduce this once in a while).
I migrated to a machine to use kernel 4.13.0-17-generic and the problem is being reproduced instantaneously. That said, I understand that the problem has something to do with the hypervisor kernel version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733864 Title: kernel 4.10.0-40 is hanging with a CPU soft lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1733864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
