    Now I would actually expect arch_trigger_all_cpu_backtrace_handler() to
    issue this warning, that said, ~700 seconds is a bit long, I'm fairly
    sure it didn't actually take that long, you'd have noticed your vm being
    'away' for 10+ minutes I'd think, no?


    There's something entirely fishy with that stuff, let me to stare at it.
