I get this device timeout when the wm interface is up, but has no carrier
(no cable connected or the switch is off where the card is connected too)
and samba is listening on this interface.
The device timeout happens every 6 hours and stops after I turn off samba.

But this is an 3.99.x kernel so I haven't reported the problem yet.

Where I can't say I have interactive problems.
