The IP fragmentation code is fine. Its just waiting Linus or
someone to fix the memory allocator to reallocate or discard pages
in patterns that build page groups. The other alternative is to
make vmalloc() type operations interrupt safe - but that is even
harder.

So its not network layer, its lower - and when the lower layer is
fixed the networking will trundle happily along as will NFS

I believe it is a combination of both subsystems being at fault, but
instead of yapping and arguing the matter I will be working with Eric
Schenk to fix things up so the skb fragmentation problems are solved
for good.
