[Bug 660302] Re: e1000e ethernet link down

[PascalCavy]

The current updated maverick kernel renders my integrated ethernet
completely unusable ! The ethernet link always stays down.

I have noticed on my ethernet switch the following difference between old 2.6.32-25.44,  current 2.6.35-22.35 and devel 2.6.36-020636.201010210905 :
- before boot at power on the link is up
- on boot the link is put down as soon as 2.6.35-22.35 is started
- on boot the links stays up with the old and devel kernel
