According to .config yes

Nope, why should I?

Disabling ME in the BIOS does not help.

Yep. Latest BIOS does not help either.

100% reproducible. I just follow the steps below:

1   plug cable
2   modprobe e1000e	-> Works 
3   rmmod e1000e

4   unplug cable     
5   modprobe e1000e
6   plug cable		-> Works not

7   rmmod e1000e
8   modprobe e1000e	-> Works not

9   unplug cable   <- This makes the difference unplug while module loaded!	

10  rmmod e1000e	
11  plug cable
12  modprobe e1000e	-> Works

Fun, isn't it?

Thanks,
