Subject: Unable to get link beat with Niagara 2264 (Intel 82571EB) and e1000e
driver on 3.4.4 (long)
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
