"Me too" (although I am running -current).

I find that WPA-EAP seems to take ages to connect and quite often it will
need me to do wpa_cli reassociate and wait before it will work.

WPA-PSK doesn't seem to disconnect very often at all for me but I have seen
it happen.

My wpa_supplicant.conf..

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
        ssid="dons"
        key_mgmt=WPA-EAP
        phase2="auth=MSCHAPV2"
        identity="username"
        password="password"
}

network={
        ssid="Genesis"
        key_mgmt=WPA-PSK
        psk="mykey"
}

The WPA-EAP AP is a WRT54G running OpenWRT, the WPA-PSK one is an Alloy
WDS24108AP (which I believe has some Atheros chipset in it)
