Kernel 3.7.9 Update - e1000e network card has issues

Just updated my kernel to 3.7.9.
Previous kernel was 3.6.11

Before update e1000e network card worked fine (I'm using wicd and dhcpcd).

After update dhcpcd times out trying to get a network address (times out on DISCOVER)

Things to note
lspci -k shows the card exists and the kernel module is loaded and correct (e1000e is compiled into the kernel not an external module).

ifconfig shows the card and I can bring it up and down HOWEVER;
Not a single byte is ever registered as transmitted or received

Finally...the leds on the network card are on while the system is booting but they turn off shortly after booting.

I'm guessing bad kernel module so I'm thinking of filing a bug with the kernel team (in other words not a gentoo problem) but I thought I'd get some ideas here first before I waste anyones time dealing with a defect report.

I've noticed a few complaints regarding the e1000e module in 3.7.9 not working until you put the system to sleep and turn it back on.
In my case that does nothing.

OK..so this is actually the final note....everything works find when booting to 3.6.11 so highly unlikely it's a config issue (unless it's a kernel config issue).

Any ideas would be greatly appreciated

Linus recently released v3.8. Does your card work correctly there?

This works fine with 3.7.4

Hi,

I got the problem with kernel 3.8.4:

The problem can be produced by doing a long term download.
Has anyone any further suggestion or is this a new problem?

Thanks!
Best regards
