We are facing exactly the same problem as described at:
Although, we have already followed all hints listed there with no success.
1) Copying with unicast runs with no problem.
2) LSPCI says that my board is:
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
It's in the server side.
3) We are using a non-managed switch
4) We have installed with Ubuntu 10.04 and it works well only one time.
Anyone has futher hints to try to figure that out ?
Thanks a lot,
