Comment 29 for bug 945379

Jack: you can at least try out the 3.9rc3 kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc3-raring/ (you need to install both linux-image and linux-image-extra before rebooting) and report back.

That said, even though a lot of commits have been put there recently [1], there are some more commits in 'linux-next' (what will become 3.10 eventually, unless some of the commits are backported to 3.9 and earlier kernels) [2]. Most interestingly, [2] has "Update initvals for AR9462" and "Fix fixed antenna for AR9462". It's somewhat harder to test as there are no pre-build kernels, but it is possible via drivers-compat backports [3] [4] - latest 2013-03-15 package again misses a couple of commits though, including a commit that says "... Running it on those queues anyway can introduce some race conditions leading to unnecessary chip resets.".

(I've personal interest in AR9485 problems on my Zenbook)
