Few notes:

- sometimes it gives: eth0      Failed to read scan data : Resource 
temporarily unavailable

Looking at the code of wpa_supplicant I see that:
  for (;;) {
                tv.tv_sec = 2;
                tv.tv_usec = 0;
                FD_ZERO(&rfds);
                FD_SET(ctrl->s, &rfds);
                res = select(ctrl->s + 1, &rfds, NULL, NULL, &tv);
                if (FD_ISSET(ctrl->s, &rfds)) {
                        res = recv(ctrl->s, reply, *reply_len, 0);

It applies a timeout of 2 seconds for the answer. Maybe the 
completantion code on ar6000 driver
wait more than 2 seconds?
