ATH9K Wireless USB adapter can't authenticate after 3.4 Kernel update

Hey!
Ever since the 3.4.2 kernel update, my wireless adapter (TP-Link TL-WN722N card using the ATH9k driver) can't connect to any network.
I can scan for available networks, but when trying to connect to one it just keeps trying to authenticate forever.
Relevant everything.log:

Jun 24 19:18:41 or-arch NetworkManager[735]: <info> WiFi now disabled by radio killswitch

This just repeats itself.
If I downgrade to 3.3.8 and reboot, everything starts working perfectly again.
I tried to look at the upstream ath9k issue tracker, but didn't find anything relevant.

Thanks!

Did you ever solved it? I have the same adapter and it does not connect here too. I am not getting the "authenticating" messages though...

I had the same problem but found a workaround in another thread here.
Before you connect open up a terminal any type:

ifconfig wlan0 promisc
