Excellent.

Just an update: this turns out to be a bug in linux rather than one
in Xen/XenLinux, and so we've reported it upstream. Hopefully it'll 
get fixed in a forthcoming version -- the only risk is that it's 
hard to trigger on non-Xen boxes (requires fragmented skb's being
received) so may not be top priority for the mainstream guys. 

We'll roll in any fix as soon as it's available.

cheers,

S.
