EAPOL frame too short error with Cisco 1200 AP

I've been trying to get wpa_supplicant to work with my Netgear MA401 card and 
Cisco 1200 APs. 
It seems to be enabling WPA and associating but i get this error message:

WPA: EAPOL frame too short, len 46, expecting at least 99

Anyone seen this before?

Here's some detailed info:

hostap driver and wpa_supplicant versions 0.2.2

The firmware versions, loaded into RAM but not yet flashed:
NIC: id=0x800c v1.0.0
PRI: id=0x15 v1.0.7
STA: id=0x1f v1.7.4

here's the config file:
network={
        ssid="ornlwpa"
        scan_ssid=1
        proto=WPA
        key_mgmt=WPA-EAP
        pairwise=TKIP
        group=TKIP
        eap=PEAP
        identity="test_user"
        password="test"
#       ca_cert="/etc/cert/ca.pem"
#       client_cert="/etc/cert/user.pem"
#       private_key="/etc/cert/user.prv"
#       private_key_passwd="password"
}

These APs have multiple SSIDs, and they advertise a different SSID 
(ornl-visitor) than the one I want (ornlwpa) so scanning is enabled.
heres the output of debug mode
