Bug Description

While testing 12.04 LTS on the XT3, I turned wireless/bluetooth off using the slider switch (the only physical on/off device for wireless, there is no hotkey). Here's the output from rfkill as I go through the test:

before using the slider:
ubuntu@201104-7598:~$ rfkill list
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

After turning wireless off via slider:
ubuntu@201104-7598:~$ rfkill list
1: dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
2: dell-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

After turning wireless back ON with the slider:
ubuntu@201104-7598:~$ rfkill list
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
5: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

Unfortuntately, there is no softkey for turning wireless off and on. there is no way to re-enable wireless without rebooting the machine at this point either.
