Comment(by lindi):

 Thanks for your analysis. I can confirm the oops you see in comment 12:

 lindi at ginger:~$ sudo sh -c "echo s3c2440-sdi > $sys_wlan_driver/bind
 lindi at ginger:~$ sudo ifconfig eth0 up
 lindi at ginger:~$ sudo ifconfig eth0 down
 lindi at ginger:~$ sudo iwconfig eth0 power off


 PC is at wmi_powermode_cmd+0x4c/0x64 [ar6000]

 Re arWmiReady I'm equally puzzled. It seems that

 arWmiReady is set to true
  since ar6000_ready_event is called
   since wmi_ready_event_rx is called with WMI_READY_EVENT
     since wmi_control_rx(.., osbuf) reads WMI_READY_EVENTID from osbuf
      since ar6000_rx calls it when arWmiEnabled == TRUE

 This would imply that arWmiEnabled can only be set to TRUE if it already
 was set to TRUE. If it is not true then ar6000_rx will not call
