    By "working", do you guys mean you're getting gigabit?

    Here are instructions on how to install kernel 3.2 to Ubuntu 11.10 x32 and x64:

    I am hopeful that this will hold the correct driver.

    I think something happened in the latest kernel (2.6.38-13, im using natty) because I did this update some time ago and now suddenly gigabit works. It loads r8169 but it works perfect

    I made changes to the source-code-tarball, so the driver r8168 can now be build with "dkms" automatically if a kernel upgrade occurs:

    Oh, I wish that SOMETHING about this driver bug was simple. I had it fixed -- and after a system crash and upgrade, I got the problem back again. Because of some peculiar circumstances, it took me a while to recognize and fix it.

    I have two systems. The older one has a Gigabyte GA-MA78-US2H motherboard, and the newer one has a GA-990FXA-UD5 motherboard, also from Gigabyte. Both of these motherboards have Realtek NIC chips. I upgraded the older system first, and watched Ubuntu automatically install the r8169 driver. To my great surprise, it worked!

    Therefore, I figured, there would be no trouble with the newer board. Initially, things looked fine. But it turned out I had a subtle problem. Instead of getting a short burst of network access followed by a long timeout, I got an alternating pattern of roughly two minutes up, followed by two minutes down. Initially, I didn't try using the network long enough to see the timeout. The initial uptime was longer, I think, than it was with an older revision of Linux. But eventually, the system would choke again. When I rolled back the r8169 driver, blacklisted it, and installed the r8168 driver, a stable connection was regained.

    Looking more closely at the motherboard manuals, I can see that my older motherboard has a Realtek 8111C NIC, while the NIC on the newer one is an 8111E. I find it weird that the new, r8169-series driver has more trouble with a newer NIC than the older one, but that's the way it is. Both systems are running Oneiric 64-bit, kernel 3.0.0.17.

    Best of luck to you all as we keep slogging through this problem!
