Well it doesnt crash my box here.

ET refuse to provide source, that means the Linux community cannot even guess what the problem might be. I always tell people not to use binary only drivers - here is why.

Always defragment does change the precise kernel behaviour and might with the right driver bug show up a problem. If so I would expect the panic to be an skb_put or skb_push panic.
