You can ignore the above message.

I find kobject debugging more distraction than help unless you are trying to
debug kobjects.

If I read the above correctly, you never got any data transmitted. Michael, is
that correct?

Others are getting the same sequence of MAC suspend
failed/BCM43xx_IRQ_XMIT_ERROR. Some people have
found that setting BADNESS_LIMIT to 0 makes them go away.
The following patch should be applied:
index d71d797..4e5ff6b 100644
--- a/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c
+++ b/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c
@@ -2518,8 +2518,7 @@ static void bcm43xx_periodic_work_handle

*/
mutex_lock(&bcm->mutex);
- netif_stop_queue(bcm->net_dev);
- synchronize_net();
+ netif_tx_disable(bcm->net_dev);
spin_lock_irqsave(&bcm->irq_lock, flags);
bcm43xx_mac_suspend(bcm);
if (bcm43xx_using_pio(bcm))
This fix was found for bcm43xx-softmac, but has not yet propagated into -d80211
in wireless-dev. It
takes care of another error that has been seen, namely NETDEV WATCHDOG tx
timeouts.
