Hostapd WPA2 and XP Supplicant

Hi,
  I have 1 last issue with hostapd. All works well except Windows XP.
I have 4 clients to test with.
1. WPA Supplicant linux
2. Nokia N95
3  Vista's Supplicant
4. And XP sp3 wpa supplicant.

They all connect ok but WinXP keeps disconnecting and re authenticating 
. Vista is OK so I sure the problem is in XP. Windows XP is no help in 
the debugging of this problem and tells me nothing. If I keep the 
interface busy with data it stays up. A few seconds of quiet on the 
interface it starts to disconnecting and re authenticating again.

Heres what I get from Hostapd.
I only included 2 authentications to save room.
