Ok, I'm making a patch...will add this to it.

How about this one.  It seems like it does a dev_put when it shouldn't
(if some of the if's fail, the dev_get never happened):

net/sched/sch_generic.c

static void dev_watchdog(unsigned long arg)
{
	struct net_device *dev = (struct net_device *)arg;

	spin_lock(&dev->xmit_lock);
	if (dev->qdisc != &noop_qdisc) {
		if (netif_device_present(dev) &&
		    netif_running(dev) &&
		    netif_carrier_ok(dev)) {
			if (netif_queue_stopped(dev) &&
			    (jiffies - dev->trans_start) > dev->watchdog_timeo) {
				printk(KERN_INFO "NETDEV WATCHDOG: %s: transmit timed out\n", dev->name);
				dev->tx_timeout(dev);
			}
			if (!mod_timer(&dev->watchdog_timer, jiffies + dev->watchdog_timeo))
				dev_hold(dev);
		}
	}
	spin_unlock(&dev->xmit_lock);

	dev_put(dev);
}
