Strangely enough, 8139cp survives with no message printed and no hang or
anything. But this is with qemu/kvm.

	static int cp_open (struct net_device *dev)
	{
	        struct cp_private *cp = netdev_priv(dev);
	        int rc;

	        if (netif_msg_ifup(cp))
	                printk(KERN_DEBUG "%s: enabling interface\n", dev->name);

	        rc = cp_alloc_rings(cp);
