If your problem is really FRTO related (that what the patch is for),
you could try to disable FRTO temporarily:
	Hi, the patch helped, but what's the conclusion? Is the problem
"solved"? Will this patch be merged in the next kernel? This thread
seems to be forgotten.
I was yesterday preparing the patch description by adding some more
thoughts to it (as if there weren't enough already) but didn't yet send it
with new cover (to sort of notify davem).

I give no guarantees about the _next_ kernel but some 2.6.26.y and 2.6.27
is more likely bet.
By the way, i had also problem with frto with local connections, and it was 
trivial to reproduce. But because of proprioetary(but i have sources) 
userspace application and specific way of using it - i didn't report to 
maillist. But after patch is ready, add me please in cc, i will test it with 
me too.

For me disabling frto helps to solve problem. With frto i have 
connections "stalling", if there is trasferred large chunks of data over 
loopback. It is complicated way how it works all - but i can try to explain 
how everything works, if required.
