Could you please send a debug log from wpa_supplicant with -dd on the
command line? I would also like to see a packet capture log showing the
EAPOL-Key frames (e.g., with tcpdump or Ethereal).

Have you been able to use that AP with EAP-FAST using any client
implementation? I'm not sure I understood the exact issue here. Is the
AP forwarding EAP-FAST/Start from authentication server to Supplicant,
but not forwarding the response to this back to the authentication
server?
