Supplicant Can't Make a Connection to a WPA Secured Access Point.

* I have an issue using wpa_supplicant but I can't say for sure if it?s a
configuration issue or a problem with the kernel it?s running on. I?m
hoping someone on this might recognize the issue. I?m running version
wpa_supplicant version 0.7.3 on linux 2.6.37 on the AM3517 processor (TI
SDK 05.05). The published SDK didn't include wireless support and I've been
adding it for the WL1271L radio. So far I have it working well enough that
I can connect to an unsecured access point using wpa_supplicant but when I
try to connect to a WPA secured access point there seems to be an error
accessing something the supplicant needs to complete the connection. I
added the -dd option to the arguments and ran it in the foreground to catch
the following error:

WPA: RX message 3 of 4-Way Handshake from 98:fc:11:8c:8b:60 (ver=2)

WPA: Failed to set PTK to the driver (alg=3 keylen=16
[  144.573486] cfg80211: Calling CRDA to update world regulatory domain

Has anyone ever seen an error like this? It looks like something in Netlink
(set_key) can?t find a file or resource of some kind. If anyone has any
advice I'd love to hear it.
