e1000e: NIC not working (afer resume?)

e1000e: NIC not working (afer resume?)

[Frederik Himpe]

I have a Dell Latitude E6400 which has a network card supported by the 
e1000e driver. Often (I think after a suspend/resume cycle), the network 
card does not work at all: the NIC is correctly seen by ifconfig, but 
running ethtool just returns: "No such device". dhclient -v gives the 
impression that it's correctly sending out DHCPDISCOVER packets on the 
NIC, but a tcpdump running on the same machine does not see any packets 
going out.

I'm using Debian's 3.0.0-3 kernel (corresponding with Linux 3.0.3).

Full lspci, .config and dmesg output at
http://artipc10.vub.ac.be/~frederik/e1000e/

Here is some relevant summary.

How can I find out what is going wrong?
