syz-executor.0/7666 is trying to acquire lock:

ffff88813fffad58 (&zone->lock){-.-.}-{2:2}, at: free_pcppages_bulk+0x68/0x660 mm/page_alloc.c:1205

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  console_owner --> &port->lock --> &zone->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&zone->lock);
                               lock(&port->lock);
                               lock(&zone->lock);
  lock(console_owner);
