I tried to make sense of the dmesg log you sent me. Not sure what is
happening so could do the following:

1. Determine wpa_supplicant version using -v option.
2. Add '-ddt' option in DBus service file:
	wpa_supplicant >= 0.7: fi.w1.wpa_supplicant1.service
	wpa_supplicant < 0.7:  fi.epitest.hostap.WPASupplicant.service
   (located in /usr/share/dbus-1/system-services/).
3. Reproduce the problem and sent /var/log/syslog.
