Right, there's no sign of the watchdog message in the journal (unless you reported the bug after rebooting the VM). In this case I'm out of ideas... We can't detect the situation in apport, and it's not a systemd bug either as these are merely consequences of the long kernel hangs, not the causes.
Upstream bumped the watchdog timeouts from 1 min to 3 mins which should make these situations at lot less likely, but ultimately this is just patching up symptoms..
