The patch that was incorporated into linux-backports-modules is not a solution, only a workaround. And it doesn't solve the issues described as stated by me and many others in the comments.
Please have a look at this kernel bug where a solution is being proposed http://bugzilla.kernel.org/show_bug.cgi?id=14267 (Disassociating atheros wlan). Quoting from the proposed bug fix: "I did a bisect yesterday on this, and the results seemed to have worked over here by reverting: 75e6c3b72b3ab01c47629f3fbd0fed4e6550bf3a cfg80211: lower dynamic PS timeout to 100ms". Hopefully this should provide a real solution.
