[Bug 1220577] Re: [HP Pavilion 15 Sleekbook] wireless hotkey function loss on 12.04.3 but works on 12.04.2
I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.
Can you test the following kernels and report back? We are looking for
the first kernel version that exhibits this bug:
v3.5 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-quantal/
v3.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/
v3.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/
v3.8-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc1-raring/
You don't have to test every kernel, just up until the kernel that first
has this bug.
One thing to note, some of these kernels require that you install both
the linux-image and linux-image-extra .deb packages, if both exist.
Thanks in advance!

Title:
[HP Pavilion 15 Sleekbook] wireless hotkey function loss on 12.04.3
but works on 12.04.2
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
CID 201209-11789
Hardware: HP Pavilion 15 Sleekbook
image: 12.04.3
Step to reproduce the bug:
1. boot into the system
2. connect to wireless AP (if any) via the indicator on Desktop (upper-right hand side)
3. if connected, make sure we could surf on internet
4. press the wireless hotkey, in this case, it is F12
Expected result:
1. the wireless will lose connection
2. no AP on the scanning list of the wireless desktop indicator
3. wireless LED will change color (from white to orange)
Actual result:
nothing happened
More information may help:
1. "rfkill list" shows the soft block was still "no" after the wireless hotkey is pressed
2. "sudo showkey -k" has no response when the wireless hotkey is pressed
3. 12.04.2 will not have this bug on the same machine
