OK, some more info. After the warning the system is usable but wireless doesn't work. The hang happens when I activate the rfkill swich. This happens even after a fresh boot. After activating the rfkill switch the console fills with: unregister_netdevice: waiting for device wlan0 to become free with a line every 5 seconds or so. At this time the system is completely unresponsive.
