Not sure what you mean by LOM. There is no Lights Out Module. I have
now removed the two ethernet cards and enabled the motherboard NIC.
I'll leave it like this. There is one ethernet card that uses a 
8139too module.
The relevant interface is:
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
	Subsystem: Gigabyte Technology Co., Ltd Motherboard

	I/O ports at d000 [size=256]
	Memory at fdd00000 (64-bit, non-prefetchable) [size=4K]
	Memory at d2100000 (64-bit, prefetchable) [size=16K]

	Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+

eth5 is the working r8139
eth6 is the r8169 that we're interested in.

That's fine. I was doing it to see if it would work. I'll stay with the r8169
for now. I got a watchdog notice now, not sure if that is better or worse.
