Setting wireless interface mode with PRO/Wireless 4965 AGN

I'm trying to set my laptop's wireless interface to run in Ad-Hoc mode. Currently the interface is in managed mode

[root@nathan-laptop /]# iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"Farfel"  
          Mode:Managed  Frequency:2.422 GHz  Access Point: 00:1C:F0:B8:4A:3F   
          Bit Rate=60 Mb/s   Tx-Power=14 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Encryption key:off
          Power Management:off
          Link Quality=100/100  Signal level:-55 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

When trying to change it I get the following error:

[root@nathan-laptop /]# iwconfig wlan0 mode ad-hoc
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Operation not supported.

To add the the mystery when I boot from an arch live cd I am able to change the wireless interface's mode. I'm using the latest iwlwifi-4965-ucode firmware as well as the iwlagn kernel module.

Does anybody know what the problem is?

The problem seems to have resolved itself after updating the kernel.
