This seems to be a repeat of an old message that I've already replied to, but I'll reply again to prevent a flood of "me to" responses.

There are two things of not. First, get yourself 2.1.37, it fixes a bug in the TCP code that might be related.
Second, if that does not solve your problem, this sounds like the classic case of a broken router between you and ftp.xcf.berkeley.edu that is mucking up on path MTU discovery. You can test this case by turning off the PMTU code on the Linux end. (This is a configuration option, so you'll have to recompile your kernel.)
