other info that might help us debug this:

Chain exists of:
  console_owner --> &dev->power.lock --> hrtimer_bases.lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(hrtimer_bases.lock);

                               lock(hrtimer_bases.lock);
