Slow outgoing network traffic from all services, yet NAT traffic is unaffected

Description of problem:
Upon upgrading to the latest kernel, all outgoing traffic from any of the services on my linux box slow down to a crawl. Going back to any previous kernel, and everything works fine again.
NAT traffic which also goes through the server, works as expected... No slow down.
The only thing thatI change to make this happen is the kernel chosen during boot. All other files remain unaltered.
I've even reinstalled FC4 fresh and reproduced the same problem.
The only configuration that I use that wouldn't be normal is that I bridge two of my ethernet adapters... eth0 + eth1 = br0 eth0 is gigabit and eth1 is 100mbit
squid, samba, ssh, apache... they all show the same slowdown... it doesn't matter if the connection is via lan (br0) or via the internet (eth2).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot system using kernel-2.6.14-1.1637_FC4
Actual Results: outgoing traffic from all services on linux server slow down to a crawl, or eventually fail.
Expected Results: no network trouble.
This is a mass-update to all currently open kernel bugs.
A new kernel update has been released (Version: 2.6.15-1.1830_FC4)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
