EAPOL-Key 2/4 Pairwise with unexpected replay counter

[/CODE]

I've been using WPA2-PSK AES with an Atheros 5212 PCI
card on a x86 machine running pfSense 1.0.1.
What does 'ath0: STA WPA: received EAPOL-Key x/x
Pairwise with unexpected replay counter' mean? It
appears every hour. :(
Is a problem on the client side (Windows XP SP2) or on
the server side (hostapd)?
I've tried to run pfSense Beta 1.2 LiveCD (not the
latest CVS) but it complains about WDMA2 used by the
harddisk drive (pfSense 1.0.1 set it as PIO4 instead).
What should I do? Daily updated 1.2 Betas have updated
atheros driver than the stable 1.0.1 version and WDMA2
bug fixed?
I can't understand why it happens. It is a wifi card
based on Atheros 5212 card and it should work on
FreeBSD for sure.

Thanks.
