Yes, it's the 82546EB that's on the motherboard. When MSI is enabled and I try to do anything with its network interfaces, the system hangs solid (won't even echo console keystrokes) at least half the time. When it doesn't hang, I get TX watchdog timeouts on both interfaces. It works perfectly if I disable MSI. John
