Created attachment 601471 [details]
Proposed patch from Ubuntu Launchpad.

Description of problem:
There's a bug which prevents the Bluetooth and WiFi radio to operate independently of each other. Turning on/off either Bluetooth or WiFi would turn on/off the other interface. This happens when using the keyboard button (Fn+F2) and gnome-shell switches from the Bluetooth and Network applets.


Version-Release number of selected component (if applicable):
3.4.6-3


How reproducible:
Always


Steps to Reproduce:
1. Press Fn+F2 to turn on or off the WiFi radio.
2. Observe that both Bluetooth and WiFi adapters turn on/off.


Alternative Steps to Reproduce:
1. From within gnome-shell turn off Bluetooth from the indicator's menu.
2. Observe that both Bluetooth and WiFi adapters turn on/off.

  
Actual results:
Both Bluetooth and WiFi radios are turned on/off.


Expected results:
WiFi and Bluetooth radios should operate independently of one another.

I re-built a kernel RPM with the above patch and it seems to work so far.

Comment 2 Dave Jones 2012-07-31 14:13:06 UTC
The rfkill code for this driver has been removed entirely upstream.
I think I'll just backport that, which would fix it for other laptops too.

Comment 3 Lorenzo Villani 2012-08-01 20:55:07 UTC
Confirming that an unpatched 3.5.0 kernel† does not exhibit the issue.


† Custom kernel package based on 3.5.0-2.fc17

Comment 4 Josh Boyer 2012-08-02 00:36:50 UTC
F16 should be getting a rebase to 3.5 next week.

Comment 5 Justin M. Forbes 2012-08-24 20:46:40 UTC
So, it is taking a little longer due to an issue seen in F17 with the 3.5 kernels. Once that is fixed, we will be pushing 3.5 to F16. Sorry for the delay, but it is still going to happen.
