Asier, I tried copying 700MB files to my lite board with ftp on sylvain's latest kernel and was not able to reproduce the problem. One thing I did see though were lots of RX framing errors. I will investigate this further.
I consulted with someone in Freescale who knows a lot more about bestcomm dma and the 5200 than me and his best guess was that there is a problem in error handling. Can you have your partner report what the error counts reported by ifconfig are? This might give us some clue about what is leading to the problem.
