Hi, After a lot of git-bisecting and other testing, it appears that commit 382a103b2b528a3085cde4ac56fc69d92a828b72 is the culprit. To reproduce the problem, use backports-20130607, and the ath9k defconfig (with no change otherwise). The station is unable to authenticate with WPA2 to the AP. Interestingly enough, if a monitor vif is created and upped beforehand, the authentication succeeds. After reverting the commit, authentication succeeds very quickly (without the need to up a monitor vif), just as expected. Note that I have kernel 3.8.0 (as per Ubuntu 13.04) and that original ath9k_htc driver works as expected. This has been also tested on Debian with driver from original kernel 3.9 (i.e. without backports). For the moment I can live with the commit reverted, but I suppose it's been there to fix something else, so this should probably be looked into by someone more knowledgeable than me.
