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:
00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03)

        Kernel driver in use: e1000e

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...

It doesn't have link.  Without link nothing can happen on the wire.
What are you expecting to happen here?

Have the device get link first.

What do you mean by "get link" ?
A network cable is plugged in the ethernet port, but it doesn't seem to be
detected in Linux 3.0 (while everything works fine in 2.6.32).

Also, it seems that link is detected when the laptop first boots, until a "MAC
Wakeup cause - Link Status Change" message:

I cannot successfully build these kernels with my toolchain (see above).

Added these lists again.

To resume what we have found up to now: when runtime PM is activated for
the e1000e NIC, it does not wake up when a cable is plugged or when
ethtool is run. Runtime PM has to be deactivated to get the NIC working
again. Apparently this problem started between 2.6.34 and 2.6.35.
