Here it works for a while with debug enabled even with wpa_supplicant,
but after a few minutes the console output stops working, but the
keyboard is still handled ok. The Caps lock led blinks when the key is
pressed and ctrl-alt-del can reboot the box.
When debug is disabled and wpa_supplicant is on, it crashes after a few
seconds and gets me into the debugger.
I'll try later with unsecured networks and see if that happens again.
