It seems the kernel panic at:

        if (skb_shared(skb))
                BUG();

in pskb_expand_head().

It maybe related to my patch:
http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commitdiff;h=210d6de78c5d7c785fc532556cea340e517955e1

You can try to revert it and test again.

However, the bug is a misuse of pskb_expand_head().
