Michael,
I still have not gotten a network guru to answer any questions about
synchronize_net, but I have been testing the patch below:
Index: wireless-2.6/drivers/net/wireless/bcm43xx/bcm43xx_main.c

mutex_lock(&bcm->mutex);
- netif_stop_queue(bcm->net_dev);
synchronize_net();
+ netif_stop_queue(bcm->net_dev);
spin_lock_irqsave(&bcm->irq_lock, flags);
bcm43xx_mac_suspend(bcm);
if (bcm43xx_using_pio(bcm))
With the synchronize_net call before the netif_stop_queue as shown, my device
has run since last Saturday with no netdev watchdog tx timeouts. Roughly two
days of that testing was done at the accelerated rate of 60X normal.
I still hope to get access to a guru, but if that doesn't happen soon, I'm going
to push this change so that it gets into 2.6.19.
