[HP ProBook 4540s] Qualcomm Atheros bluetooth properly works with Ubuntu 16.04 LiveUSB but not on a fresh install

[Jordi Sayol]

I've tested my notebook with Ubuntu 16.04/17.04 (64-bit) LiveUSB pen drive and the mini-pci Qualcomm Atheros QCWB335 [168c:0036] properly works, both wifi and bluetooth.

After a fresh install from the same LiveUSB pen drive, the bluetooth does not work.

$ bluetooth
bluetooth = none (no device)

Pressing the WiFi button turns off WiFi, and does not enable bluetooth. Pressing it again turns WiFi on, but bluetooth remains off.

WORKAROUND: Suspend, and unsuspend the laptop.

Jordi Sayol, thank you for reporting this and helping make Ubuntu better.

To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

Jordi Sayol, to advise, you don't have to apport-collect to a report unless specifically requested to do so. Despite this, could you please advise to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653274/comments/17 ?

[Jordi Sayol (g-sayol)]

Sorry for the "apport-collet". My mistake.

No changes on Ubuntu daily-live (December 31th 2016). Exactly the same behaviour, bluetooth properly works when run the LiveUSB pen drive but do not works after a fresh install using the same pen drive.

Note that I always used Ubuntu MATE on all the tests.

[penalvch (penalvch)]

Jordi Sayol, to clarify, if you click on your keyboard the WIreless Button once, does the bluetooth turn on, and the WiFi remain on?

[Jordi Sayol (g-sayol)]

No, if I press the wlan button, wifi turns off and bluetooth keeps missing. If pressed again, only wifi reactivate. Bluetooth alwais keep missing, like there is not a bluetooth device.

Another behaviour discovered. If I "Suspend" my notebook, when reactivate, the bluetooth works! and wifi remains working too.

[penalvch (penalvch)]

Jordi Sayol, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed.

Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

Thank you for your help.

rfkill list

[Jordi Sayol (g-sayol)]

$ rfkill list

bluetooth = none (no device)

Same behaviour with kernek 4.10 RC1. Bluetooth device is missing.

[penalvch (penalvch)]

Jordi Sayol, would anything change if you disconnected the below, restarted and then tried the WiFi keyboard combo:
Bus 003 Device 002: ID 046d:c52f Logitech, Inc. Unifying Receiver

[Jordi Sayol (g-sayol)]

Christopher M. Penalver, I don't understand you. I do not have any "wifi keyboard combo". I guess it was a thread mistake.

[penalvch (penalvch)]

Jordi Sayol, as per the user manual downloaded from HP.com, it does have a WiFi keyboard button. Could you please read it and advise?

[Jordi Sayol (g-sayol)]

Christopher M. Penalver, Yes, there is a wlan button with a led. By default all devices are activated (led white). when pressed, led becomes orange indicating that all wireless devices (wifi and bluetooth) are deactivated. When the button is pressed again wifi reactivate, but bluetooth never. Bluetooth is only active (device present detected by Linux) after Suspend/reactivate the computer.

I have a question for you. If this is a Linux kernel problem, why this wireless device works like a charm when the computer is boot by the Ubuntu liveUSB pen drive?

[penalvch (penalvch)]

Jordi Sayol, one way to help confirm if this is a regression in the linux kernel is to test the version that comes with the Live environment 4.4.0-21.37.

[Jordi Sayol (g-sayol)]

Christopher M. Penalver, sorry for the delay. I've booted liveUSB and installed the last three Ubuntu LTS (12.04.5, 14.04.5 and 16.04.1) and all of them have the exactly same behaviour. When booted from the LiveUSB, both WiFi and BLuetooth works like a charm, but when booted after a fresh install, Wifi works and bluetooth is not detected (no device installed), and in all the cases, after a system "Suspend", Bluetooth is detected again.

I don't know what's the source of this problem but I'm quite sure that this is not a simply regression on a kernel version.
