Is this happening to all of your clients or just a few ? Was this always happening or just started ?

We're migrating off of Odyssey Client to the native Windows supplicant. It seems that only a few of them are having this issue. I've updated the drivers for the WLAN card and it still happens. It isn't just on a particular wireless NIC or vendor specific. It does only seem to happen on the older 1230 and 1240 APs and not the 1140 or 3500 APs. The laptops connect via ACS 802.1x through 6 WiSM 1 WLCs and use dynamic vlan redirects in ACS. The rest of the debug shows the discover, offer, request and ACK but no response from the client.
