In my experience (and as I understand the situation) if garbage is writen to
the "chan", it is caught by the check and device is dead-until-reboot anyway.
On 3.0, even without checks device was dead-until-reboot, but no crash
happened. All these checks do is converting "panic" to "WiFi broken" for 3.2.
