dmesg 4.12 kernel with working mouse

After updating my HP SPectre x360 machine wich running Fedora 26 from kernel-4.12.14.300 to kernel-4.13.5-200, my Logitech MX Master mouse isn't working anymore. There were some issues before (see: https://bugzilla.kernel.org/show_bug.cgi?id=194815). 

With firmware version 27.541033.0 my mouse working smoothly without any modification in iwlwifi.conf file. My mouse was recognized properly

But after upgrading my machine my mouse with the new firmware, my mouse isn't recognized anymore.

8265 firmware with debug enabled

Hi,

Here is the firmware for 8260. Please copy it to /lib/firmware (I assume your distro takes it from there), you can backup the existing one before you overriding it.

The instructions on how to collect the data are here:

Hello,

It took probably one week to perform this action. My laptop is last week crashed and sent back to the vendor. When I received my laptop back I will install the latest firmware.

Great. Thanks :)

This is likely duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=197061

@bart, could you try a workaround of disabling the WiFi+Bluetooth coexistence, as discussed in the above mentioned bug?

You can do it by creating file:
/etc/modprobe.d/iwlwifi.conf
with content:
options iwlwifi bt_coex_active=0
and reboot

Sadly enough HP (the vendor of my laptop) told me that the don't have spare parts for my laptop and i did not receive back my laptop. I can choose another HP device. That means that I'm not able to perform the suggested action, because I don't have the hardware anymore.

For now I suggest to close this issue.

Comment 7 Emmanuel Grumbach 2017-11-11 21:25:36 UTC

Thanks for letting you know.

In case you get another HP device with an Intel wireless / BT device and you still have issues, don't hesitate to reach out to us!

I have HP device with Intel 8265 and the same symptoms. In my case the issue is caused by https://bugzilla.kernel.org/show_bug.cgi?id=197061
