We did experienced really weird issues (non-roaming ) with 10.8 but haven't seen many issues with 10.9 yet .
Symptom :
- Device will have session going and out of nowhere it drops and it takes a while to reconnect , and according to the packet capture the device starts the EAPOL converstation and it never responds to the identity request send from the controller

- The other issue we saw was the device is able to associate / authenticate gets a valid IP address but then is unable to reach anything on the network, but in the packet capture you can see that the device is sending the traffic but not replying
I saw this issues on 6.2.1.3 and on 6.3.1.x after users upgraded to 10.9 we haven't these issues again
