skb_over_panic is only called when skb->tail > skb->end, in your case
there's still room for 3884 bytes. Are you using any external patches/
drivers/...? If so please try to reproduce without them, otherwise
please post the full oops and disassembly of __nfa_fill.

Hi Patrick,

Thanks you for the feedback.

Yes I'm using some external netfilter patch (Openwrt distribution). I'll 
look at them in more details to see if 
the root cause of the crash come from there.
