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.
