This is the same crash that you originally reported. The driver was
referencing a NULL SKB because the skb_shinfo(skb)->nr_frags was
modified on the previous packet in the TX ring.
If you had applied my debug patch #1 that I posted several weeks ago, it
should have avoided this because we should have saved away the nr_frags
for every packet on the TX ring.
