I'm using two i350 components (as two mini PCIe modules).
Every module has i350 with x1 lane of PCIe and two 10/100/1000 ethernet interfaces.
I'm using only 3 out of 4 ethernet interfaces available and I'm configuring them to 100 FULL duplex (the 4th interfaceis disabled in device manager)
I also use a 82579 on my board as10/100/1000 ethernet configured auto negotiation.
OS= win XP
During normal operation one of the 100Mbps ports disconnect for few second and connect again .
I see Event ID 27 in the event viewer of the operating system.
BIOS is updated.
What is the reason and how can I solve it.
