random problems with wpa_supplicant

[kaaposc The One]

Hello!

I will try to describe my situation.
my system: Acer Aspire 5520 notebook with AR5BXB63 wireless interface
driven by madwifi (with special hal for this atheros chip), archlinux,
wpa_supplicant 0.5.10.
my config file for connection:

# --- conf file starts ---
ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=2

network={
	ssid="REMOVED"
	bssid=00:12:xx:xx:xx:xx
	pairwise=CCMP
	group=TKIP
	proto=WPA2
	key_mgmt=WPA-EAP
	eap=LEAP
	auth_alg=LEAP
	identity="kaaposc"
	password="REMOVED"
}
# --- conf file ends ---

my problem: wpa_supplicant occasionally connects with first try,
sometimes I have to terminate and re-launch it several times to get
connection. I caught -dd output in two separate files - one with
successful connect, other with failed. should I publish them or mail
to someone who would find them useful?

thanks,
kaaposc
