Connectivity issues with Cisco controllers and PMF enabled Moto X (Gen 2)

New Moto X (Gen 2)  has PMF (802.11 w)  enabled by default . This is creating connectivity  problem with many Cisco controllers which runs old firmware . 

On sniffer analysis , we observed that cisco AP is sending  wrong key descriptor version value (3 here) in EAPOL Key1/4 and so the device is not responding with Key2/4. 

From our ( I am from Motorola Mobility) follow up with Cisco some time back , we got confirmation that issue can be similar to  CSCua29504.

Can you please advice your customers to upgrade their controller firmware to avoid issues with PMF enabled client devices ? 

http://dallasgutauckis.com/2014/09/26/wi-fi-issues-on-moto-x-2nd-gen/  is  a link to a post where user confirmed that a firmware upgrade resolved the connectivity issue seen with his work WiFi.

We were seeing issues with APs,

  Cisco Aironet 1260 Series
  Aironet 1130AG series
  WAP4400N
  AIR-LAP1242AG

and mostly from enterprise users.

Can you please confirm this was a know issue with these products and a firmware upgrade will resolve this issue ?
