[HP Pavilion 15 Sleekbook] wireless hotkey function loss on 12.04.3 but works on 12.04.2

[Taihsiang Ho]

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

12.04.3 ships with the 3.8 kernel whereas 12.03.2 ships with the 3.5 kernel. Would it be possible for you to test the latest 3.8 upstream kernel to see if the issue exists there as well:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.7-raring/

[Taihsiang Ho (tai271828)]

CID 201208-11466 with 12.04.3 has this bug as well

Kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.7-raring/
has this bug.

[Taihsiang Ho (tai271828)]

CID 201208-11466 with 12.04.3 has this bug as well

Kernel
3.8.13.2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.2-raring/
has this bug.

[Taihsiang Ho (tai271828)]

CID 201208-11466 with 13.04 has this bug and "uname -a" showed the kernel is:

3.8.0-19-generic #29-Ubuntu

[Joseph Salisbury (jsalisbury)]

It would also be good to know if this has already been fixed in the latest upstream kernel. Can you test the v3.11 final kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/

[Taihsiang Ho (tai271828)]

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/ failed
(tested on CID 201208-11466 with 12.04.3 and 13.04)

[Joseph Salisbury (jsalisbury)]

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!

[Taihsiang Ho (tai271828)]

the bisect result is:
v3.5 final: passed
v3.6 final: passed
v3.7 final: failed

all the kernels tested on 12.04.3

[Taihsiang Ho (tai271828)]

more on comment 30:
the result were done on machine CID 201208-11466

[Joseph Salisbury (jsalisbury)]

Thanks for testing. We next need to identify the first 3.7 release candidate that introduced the bug.

Can you test the following kernels and report back? We are looking for the earliest kernel version that exhibits this bug:

v3.7-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc4-raring/

If v3.7-rc4 does not exhibit the bug then test v3.7-rc6:
v3.7-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc6-raring/

If v3.7-rc4 does exhibit the bug then test v3.7-rc2:
v3.7-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc2-raring

Thanks in advance!

[Taihsiang Ho (tai271828)]

I tried 12.04.4 today and the bug is still there.

[Joseph Salisbury (jsalisbury)]

Were you able to test any of the kernels requested in comment #32?

Also, it would be good to know if this bug still exits in the latest mainline kernel. It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc5-trusty/

[Taihsiang Ho (tai271828)]

CID 201209-11789:
v3.7-rc2-raring
v3.7-rc4-raring
v3.7-rc6-raring
the display could not work normally.

CID 201208-11466 has this bug with:
v3.7-rc1-raring
v3.7-rc2-raring
v3.7-rc4-raring
v3.7-rc6-raring

[Joseph Salisbury (jsalisbury)]

So just to confirm, v3.6 final does not have the bug, but v3.7-rc1 does? If that is the case, we can bisect between those two versions.

Also, can you give the v3.14-rc6 kernel a test if you have a chance:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc6-trusty/

[Taihsiang Ho (tai271828)]

v3.14-rc6 does not have this bug. (the wireless hotkey works) on CID 201208-11466

And yes, v3.6 final does not have the bug but v3.7-rc1 does.

[Joseph Salisbury (jsalisbury)]

I started a kernel bisect between v3.6final and v3.7-rc1. The kernel bisect will require testing of about 13 test kernels.

I built the first test kernel, up to the following commit:
24d7b40a60cf19008334bcbcbd98da374d4d9c64

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1220577

Can you test that kernel and report back if it has the bug or not. I will build the next test kernel based on your test results.

Thanks in advance

[Taihsiang Ho (tai271828)]

The kernel provided in comment #38 (comment from the above) works on CID 201208-11466 with 12.04.2
(wireless hotkey and its LED works)

[Po-Hsu Lin (cypressyew)]

Question answered, revert to Confirmed

[Joseph Salisbury (jsalisbury)]

Before we continue the bisect, can you apply the latest updates and confirm the issue still exists?

[Taihsiang Ho (tai271828)]

kernel 3.8.0-39 of 12.04.3 on CID 201208-11466
could reproduce the bug.

[Joseph Salisbury (jsalisbury)]

Can you also give the latest mainline kernel one more try before I continue the bisect? It is available for download from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic/

[Po-Hsu Lin (cypressyew)]

Wireless key on 201210-11859 (HP ENVY 6 Sleekbook) works with 12.04.5 stock Ubuntu (The wireless LED works as well).
I will go through other systems that listed in tags to make sure this bug could be set to Fix-Released.

[Po-Hsu Lin (cypressyew)]

The wireless and its LED works as expected with 12.04.5 on:
201209-11789 / 201208-11466 / 201209-11731

We no longer possess 201206-11167

Therefore, I will mark this bug as "Fix-Released".
Please feel free to open a new one if you're still experiencing this issue.
