Martin,
This might be Samba specific problem, as reported here before by other user. I use NFS and had tested copying large files without seeing any problem.
Do you have NFS setup? if you do, try that to make sure.
I think there is some TCP buffering problem somwhere in the Marvell mvneta driver. But need to take time to track it down.
