EAPOL-Key timeout issue

Hi,

I have wireless internet set up in a Debian host through hostapd
0.6.10, nl80211 driver and an Atheros-based card, which on lspci reads

04:00.0 Ethernet controller: Atheros Communications Inc. Atheros
AR5001X+ Wireless Network Adapter (rev 01)

I'm trying to use WPA2 in this set up through the following config:

interface=wlan0
driver=nl80211
ssid=dMaggot

auth_algs=1

channel=1
debug=4

wpa=2
ignore_broadcast_ssid=0
<passphrase removed>
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

and, when trying to connect to this access point with a laptop, I can
establish a connection, but it eventually dies and I have to
reconnect. Debugging around, I get the following output from hostapd:

Feb 14 21:02:13 localhost hostapd: wlan0: WPA rekeying GTK

Feb 14 21:02:16 localhost hostapd: wlan0: STA 70:1a:04:b5:88:1b IEEE
802.1X: unauthorizing port

which makes me think someone is playing things wrong but I don't know
where to start debugging. For me, it's obviously something wrong with
the access point since I can connect to any other WPA2 network I see
around with the same laptop.

Any ideas of where/how can I start working in a fix for this? Thanks in advance.
