Folk, Apparently linux-net is now a spam-bucket. Apologies if you get this twice. Clifford Heath. Begin forwarded message:

I have a question that hopefully someone can answer. I recently upgraded my Debian system (a Dell Optiplex GX270) from a 2.6.16.11 kernel to a 2.6.30.5 one (current stable). My networking is now misbehaving. POP, IMAP, and NNTP connect ok (multiple packets each way, viewed using a logging proxy) but as soon as a message should start coming down, the connection hangs and then times out. I think it's the first large packet that causes this, and I saw that the linux-net team have been working on some features to increase throughput through read aggregation or something... I think it's broken (on my hardware at least). My kernel .config file and the output of "lspci" are included below. Thanks for any help you can give. Let me know if you need more information.
