Just one addition, the log before contains dmesg output too. The task that hanged was systemd, it might be related with some VMs from the previous boot record being restarted automatically, but it still doesn't explain the crash.
Rebooting the node again with 4.4 did not result in kernel crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1672521 Title: ThunderX: soft lockup on 4.8+ kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1672521/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
