But, only in Gb Mode of the 8169 NIC, with 100Mbps it is ok. http://forums.gentoo.org/viewtopic-t-570392.html I have: 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) That must be the issue, time to buy an Intel PCI-e NIC if I want better performance with samba in Linux. I do have another one of these motherboards (ABIT AW9D-MAX) running XP and it does not seem to suffer from this problem, I guess the [proprietary? Realtek driver does not suffer from this bug]?
