I just tested in qemu:
- suspend to mem
the kvm support gives a few warn ons due to sleeping spinlocks in
apf_task_wake_all(). Without it, it works just fine.

- suspend to disk
I see very often "NOHZ: local_softirq_pending" warnings. It looks
like the softirq thread is going down and the timer softirq isn't
handled for instance. Apart from this warning I see the going into
suspend and waking up.
