No, this does not happen on the mv64360. As I recall, that message occurs when something attempts to queue a packet to a driver that has called netif_stop_queue() but hasn't yet called netif_wake_queue(). I would guess that when you turn debug on, you are changing the driver logic in addition to the timing. -Dale _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
