Fedora 7 & 8 dom0 Crashes Due to domU Traffic Shaping

A Fedora 7 dom0 I have crashes with null pointer dereferences in tcp_tso_segment. After upgrading to F8 this is still happening. This seems to stem from traffic shaping in a busy domU fedora mirror server. Poking around it looks like this bug http://lists.openwall.net/netdev/2007/02/09/16 Well, they fixed that by twiddling net/ipv4/netfilter/ipt_REJECT.c but I think something in my Xen enviro with a combination of a busy bridge and traffic control rules is still tripping up on net/ipv4/tcp.c line 2241 "skb = skb->next;" from what I can decypher.
