Comment 1 Josh Boyer 2012-04-16 15:46:19 EDT
I recall a similar issue in the b44 driver that was fixed with commit 15ac2b08a2fd0f4aacbe8ae39788252fea6fbe63, however that might not be the same issue here.
Comment 2 Larry Finger 2012-04-16 16:48:13 EDT
I don't think it is the same. That patch for b44 changed a dev_kfree_skb() to dev_kfree_skb_irq(). In this case, the call is kfree_skb(). In addition, the call is inside a spin_lock_irqsave() / spin_unlock_irqrestore() pair. If I understand locking correctly, interrupts should be disabled here.
This warning never triggers on my system. Any thoughts on why it happens here?

I see some conntrack routines in the traceback. Does it still fail if the firewall is disabled?
Comment 3 Larry Finger 2012-04-30 00:10:59 EDT
I asked a question that has not yet been answered!
Comment 4 John W. Linville 2012-04-30 09:54:53 EDT
cameron, can you recreate this issue with the firewall disabled?
