"Must"?  So you've proven that the ack-every-22 packets behavior
is due entirely to the sender?

If you put 2.6.9-current on both ends and this makes things go smoothly
that is an important data point and nobody else is seeing the behavior
you are at the moment.

Personally, all of my bets are on the 2.6.5 frankenstein kernel
as the culprit :-)
