ath wpa_supplicant timeouts on AR5416

[Maciej Milewski]

Hi,
I have problem with card based on AR5416 (TL-WN861N) on 9-CURRENT.
wpa_supplicant timeouts while connecting to 11g WPA/WPA2 network:
#wpa_supplicant -iwlan1 -c /etc/wpa_supplicant.conf
Trying to associate with 00:14:6c:6a:xx:xx (SSID='NET5' freq=2462 MHz)
Authentication with 00:14:6c:6a:xx:xx timed out.
and so on.

I'm sure that network is working because I can complete the negotiation on my 
two other atheros based cards. Only the AR5416 has issues. 
#wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf                                                                                                                                                         
Trying to associate with 00:14:6c:6a:xx:xx (SSID='NET5' freq=2462 MHz)
Associated with 00:14:6c:6a:xx:xx
WPA: Key negotiation completed with 00:14:6c:6a:xx:xx [PTK=CCMP GTK=TKIP]
CTRL-EVENT-CONNECTED - Connection to 00:14:6c:6a:xx:xx completed (auth) [id=0 
id_str=]

The one which is problematic is:
ath1: <Atheros 5416> irq 1 at device 18.0 on pci0
ath1: [ITHREAD]
ath1: AR5416 mac 13.10 RF2122 phy 8.1
The rest which is working:
ath0: <Atheros 5212> irq 0 at device 17.0 on pci0
ath0: [ITHREAD]
ath0: AR5212 mac 5.6 RF5111 phy 4.1
ath2: <Atheros 2413> irq 2 at device 19.0 on pci0
ath2: [ITHREAD]
ath2: AR2413 mac 7.8 RF2413 phy 4.5

The wpa_supplicant.conf isn't complicated:
network={
        ssid="NET5"
        psk=thelongpskphrase
}

AFAIR this card was working fine in hostap mode.

How can I help in fixing the issue?
