other info that might help us debug this:

Chain exists of:
  console_owner --> &pool->lock --> (worker)->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock((worker)->lock);
                               lock(&pool->lock);
                               lock((worker)->lock);
  lock(console_owner);
