I have had the same problem, but I was using the 2.4.8 kernel ( in a production environment ). I reverted back to 2.2.19, with no changes.
I believe that the problem in my case was the 3COM drivers, 3c90x. I have now changed the driver to the 3C59x, which seems to work fine. Although the symptoms are similar, I had problems with the transfer deteriorated over time. I use rsync to take client backup from windows software to a local server, using samba mounts. The backup is then written to tape. Real nice solution and all, when it works.
