Should I understand that the LOM fails on Linux with a naked motherboard ?

Please check if runtime resume is disabled (/sys/bus/pci/devices/.../power/control
should be 'on'). If so and you do not see many netdev watchdog messages either,
these could be real link status change events.

Please do (and send a complete dmesg).

Your previous posting suggests that the LOM board is a 8168b but I haven't
seen its XID.

It could help to check the add-on 8168c in a different computer whose
motherboard does not include any networking chipset from Realtek (nor
any bios that could confuse different revisions of those).

Please don't switch between the r8168 and the r8169 modules at runtime.
I saw it in your dmesg and I won't claim it's supported.

I'll be out for work during two days.

Thanks.
