Hi,

I get the same symptoms as the ones reported by Frederik Himpe in
http://www.spinics.net/lists/netdev/msg174336.html
(Sorry for starting a new thread, I could not find a mbox archive of netdev)

My config:

running Linux 3.1rc4.

Symptoms:
network doesn't work.
ifconfig shows the device, but ethtool eth0 says:
# ethtool eth0
Settings for eth0:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available

On a friend's laptop (also Dell latitude E4300, running Linux 3.0), things work
fine. lspci -vvv of the working laptop:

The only thing I understand so far is that my NIC seems to be stuck in D3...
