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.
