Can you check if wpa_supplicant gets started twice after
"/etc/rc.d/netif restart"?
I have the feeling that this is a more or less known issue, a race
between devd (/etc/pccard_ether) and /etc/rc.d/netif. There is a small
window (a few ms) where this can happen and our net80211 isn't capable
of handling two running wpa_supplicants on the same interface. Which
leads to all kind of weird issues, .e.g. panics.
