The docker1-tcn machine with vanilla kernel 4.4.70 is still up. And on another (abmfn-staging) machine with 4.4.0-78 I've seen the crash. According to dmesg output in the console, btrfs and other fs modules were loaded. Probably due to an update-grub call.
After restart, I ensured that those modules were not loaded. No crashes have happened there since. In all cases, the machines were running on a proxmox cluster, with "Linux 4.4.24-1-pve" (pve-kernel-4.4.24-1-pve 4.4.24-72) on the host OS. With KVM version pve-qemu-kvm 2.7.0-8. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1691741 Title: Execute NX-protected page - 4.4.0-78-generic - kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1691741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
