The bug reporter in bug 1713751 has been unable to reproduce the bug with the 4.13.0-16-generic kernel. He's re-testing with the original kernel that exhibited the bug to ensure he can reproduce it consistently. If he finds that 4.13.0-16-generic is really good he really might be hitting a different bug. I'll update this bug with that answer.
laney, we could start a bisect in this bug at the same time if you want. The first thing we would have to do is identify the last "Good" Ubuntu kernel and first "Bad" Ubuntu kernel. That would mean trying some of the earlier 4.13 kernels, based on that, some 4.12 kernels, etc. Bug 1713751 suggests that he is unable to reproduce the bug with 4.10.0-33, so maybe you could try that one next? It's available from: https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/ppa/+build/13234886 Based on what you see with that, we can decide jump to the middle of the versions and try a 4.11 or 4.12 based kernel? ** Changed in: linux (Ubuntu Artful) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Artful) Status: Triaged => In Progress ** Changed in: linux (Ubuntu Bionic) Status: Triaged => In Progress ** Also affects: linux (Ubuntu Zesty) Importance: Undecided Status: New ** Also affects: qemu-kvm (Ubuntu Zesty) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Zesty) Status: New => Incomplete ** Changed in: linux (Ubuntu Zesty) Importance: Undecided => High ** Changed in: linux (Ubuntu Zesty) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730717 Title: Some VMs fail to reboot with "watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
