Here are packet traces from the working (2.6.16) and non-working (2.6.17) kernels.
The differences I see are widely varying "window sizes".
What would cause this?
Here's a partial trace of the working connection 2.6.16.18:

The client machine is "silvy", my firewall/dns box is "zippy",
and 216-145-246-23 is www.everymac.com.
The differences begin really early in these traces,
with 2.6.16.18 using a win size of 1460,
and 2.6.17-rc6 using a win size of 92 ???
