From what I can see on the image, the instruction that was executed is 0f 0b, that is ud2. That means, BUG() has beed triggered in skb_put(). Looks like the only place it could happen is http://lxr.free-electrons.com/source/net/core/skbuff.c?v=3.10#L1286: if (unlikely(skb->tail > skb->end)) skb_over_panic(skb, len, __builtin_return_address(0)); skb_over_panic() invokes BUG() to report a critical error. That means, 'skb->tail > skb->end' is true. I cannot say yet why. May be the developers of e1000e could help.
