23. Packet Loss on Intel® 82579 Gigabit Ethernet Controller
Problem: Systems with Intel 6 Series Chipset and Intel C200 Series Chipset using the Intel 82579 Gigabit Ethernet Controller may experience packet Loss at 100 Mbps and 1 Gbps speeds when the link between the Intel 82579 Gigabit Ethernet Controller and the PCH Integrated LAN Controller is exiting the Low Power Link (K1) State.
Implication: Implications are application and Internet Protocol dependent.
Workaround: A BIOS code change has been identified and may be implemented as a workaround for this erratum.
Status: No Plan to Fix.
I believe this problem can be due to a HW problem already described in an Intel errata:
