I was having a similar problem using ftp or smbclient to an NT system when I
used the new Linux kernels (2.2.2, 2.2.3)  It would send the first 20-30K and
then stall ... send the next 10K and then stall .... If I switched back to
version 2.0.36 of Linux everything worked fine.

I tried changing everything I could think of and nothing helped until I
switched both cards from full duplex to half duplex.  The xfer rates when
back to +800K on a 10 Meg Ethernet connection.
