All,

(please CC me as I am not subscribed to netdev)

I recently acquired an Interface Masters Niagara 2264 quad-port GigE 
network card, based on the Intel 82571EB network controller (see 
http://www.interfacemasters.com/products/2264.html for details). Prior 
to using it in a new system I'm planning to build I decided to try it 
out on my desktop system, which uses as Asus M4A89TD/PRO USB3 
motherboard with the AMD 890FX chipset and a BIOS dated 03/08/2011, 
running Debian 6.0.2.1.

I added the e1000e driver to my Linux 3.4.4 kernel config as a loadable 
module and inserted it, and got the following:

After doing so, though, I was unable to get a link beat on any of the 
four RJ45 ports. I tried the Intel-supplied e1000e driver on the same 
kernel and got the following:

I tried rebooting since switching to the new driver and it hasn't made a 
difference. I did a bunch of digging in Google and couldn't find 
anything that conclusively suggested a problem - I found lots of stuff 
about BIOS bugs when dealing with ASPM, old regressions fixed in 
previous kernels, and so on, but nothing that specifically identified my 
problem.

Does anyone have any suggestions? I can try Linux 3.5 very easily and if 
necessary I can also learn how to fetch a git tree and bisect it. I also 
sent an e-mail to the manufacturer asking for assistance with this 
device but I haven't received a response yet.

Thanks,

Brad
