I missed the start of this thread, but I have also seen scp stalling on 8-STABLE, except in my case it as inbound ... i.e. uploading to the FreeBSd machine. The client was scp on OSX, though I also saw the same issue with rsync, leading me to belve taht the problem lies somewhere in ssh. In the end I just used NFS and didn't worry too much about it, but just a me too to show it's not just the OP.
