other info that might help us debug this:

Chain exists of:
  (console_sem).lock --> &rq->__lock --> &ctx->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&ctx->lock);
                               lock(&rq->__lock);
                               lock(&ctx->lock);
  lock((console_sem).lock);
