I've been looking at a similar set of symptoms which sounds like it could be the same problem. Ever since I upgraded to 2.2/2.3 kernels (about two months ago) throughput between my two boxen on a private ethernet segment has dropped by a factor of over 100 from almost half a MB to just a few KB per second. tcpdump shows only a few packets per second and ifconfig shows 1 carrier error about every 2 seconds on the tx side and the same number of frame errors on the rx side. The send queue on the tx side gets filled to capacity and stays there until the transfer is complete. I think this is a network stack problem and not a hardware problem because ping -f gets 0% packet loss (one run lost 10 packets out of 60,000). This only happens with bulk transfer, interactive sessions are perfectly fine.
