Kernel >=5.9 breaks bluetooth mouse connection

Hi everyone !

I just update my kernel to 5.9.1 and my Logitech Anywhere MX 2 mouse does not reconnect after a reboot.
I have to re-pair it at each boot to get it working. Trying to reconnect it returns a connection abort in blueman-applet.
I was unable to get any more detailed logs in journalct/dmesg/bluetoothctl

Got the same behavior with 5.9.0 Downgrading to 5.8.14 solves the issue.

Bluetooth card is a Intel AX200 card.

Anyone's getting this ?

Re: Kernel >=5.9 breaks bluetooth mouse connection

Yes, it's exactly the same for me, in my case the mouse is Logitech MX Vertical and bluetooth controller is Intel Corp. Bluetooth 9460/9560 Jefferson Peak (JfP). On the other hand, already paired bluetooth headsets do reconnect and work after reboot (I have tried with Sony WI-1000XM2 and Bose QuietControl 30).

Re: Kernel >=5.9 breaks bluetooth mouse connection

Same for me too with AX200 + Anywhere MX 2S. The mouse is a BLE device I believe.

I also have a Sony MDR-1000X Bluetooth headset (not BLE) which works perfectly fine. I suspect the problem happens with BLE only.

Re: Kernel >=5.9 breaks bluetooth mouse connection

Intel AC 9560.
Both the mobile phone and the Bluetooth headset can be connected normally. However, a Bluetooth mouse that only supports BLE cannot automatically connect.

Look the file /var/lib/xxx/yyy/info
Phone/headset:
...
SupportedTechnologies=BR/EDR;LE;
...

Mouse:
...
SupportedTechnologies=LE;

Re: Kernel >=5.9 breaks bluetooth mouse connection

Same for my Logitech MX Master 2S + AX200 and I have to downgrade to kernel 5.8 to solve the issue.

Re: Kernel >=5.9 breaks bluetooth mouse connection

The same here with Bose QC35 headset. Was working great for a long time over bluetooth. Noticed yesterday after upgrade to kernel 5.9.1 - headset didn't reconnect to its profile. I had to delete the profile and pair it again. It then connected and worked ok. This morning - trying to re-connect - it kept saying it is "connecting". I could see some traffic shown in Blueman, but connection didn't succeed. I again needed to remove the device and pair it again - and then it worked.

I checked and all the drivers seem to be loading fine:

$ lsusb | grep -i bluetooth

$ lsmod | grep -i bt

raid6_pq              122880  1 btrfs

Noticed interesting errors in dmesg that I don't see were there before:

That "killing stalled connection".... hmmm - never happened before. EDIT: That was me walking out of range - it is ok.

But this "Ignoring error of Inquiry Cancel command" on second 78 after boot - this is when I turned my headset on i think and it didn't connect...

Looks like something got screwed up in the kernel and it doesn't seem to be specific hardware or driver - something in the kernel that manages BT.

EDIT 2: Some parse errors from bluetoothd in journalctl - that can't be right:

EDIT 3: Looks like in most cases, when I turn on a bluetooth device and as it starts connecting - restarting bluetooth.service gets the devices connected again:

sudo systemctl restart bluetooth

With my headphones though it is always asking to accept the device - so it looks like it is kind of "stuck" in the pairing mode or something...

Re: Kernel >=5.9 breaks bluetooth mouse connection

Yes I think something has been modified in the kernel resulting in this behaviour.
If I remember well there was some Bluetooth related corrections made recently about security issues.

Re: Kernel >=5.9 breaks bluetooth mouse connection

It already happens in kernel 5.9.0, which is before the security fix (5.9.1).

Yup, having exactly the same problem on 5.9.1 with the MX Anywhere 2S. Downgrading to 5.8 kernel series fixes the issue.

Re: Kernel >=5.9 breaks bluetooth mouse connection

@all people having the anywhere mx 2. Even on 5.8 I noticed that the mouse reconnects after session is opened but then freezes for 2 seconds and next reworks ok.
Already tried a lot of thing especially tweaking power management (usb autosuspend) but nothing really fixed the problem.

Has anyone fixed this ?

Not yet. Similar symptom occurs when testing under Debian & Fedora.

Re: Kernel >=5.9 breaks bluetooth mouse connection

Same with Intel AX200 and Logitech M590.

A temporary solution is to disable Link Layer Privacy.

My patch:

 #define use_ext_scan(dev) (((dev)->commands[37] & 0x20) && \

With the above patch, my bluetooth mouse is able to reconnect again.

Re: Kernel >=5.9 breaks bluetooth mouse connection

Has anyone reported upstream to kernel bugzilla on this issue?

There are already other upstream reports of issues with bluetooth for kernel >5.9 such as https://bugzilla.kernel.org/show_bug.cgi?id=209717 and https://bugzilla.kernel.org/show_bug.cgi?id=209403

What if you apply https://github.com/torvalds/linux/commi … 4080d6e766

If the above fails what if you revert https://github.com/torvalds/linux/commi … eb55a22beb does that work?

Applying c0ee0644df5da3f877a53e402d03634080d6e766 doesn't help.

Reverting e1d572357599d142df5764b39731b6eb55a22beb causes conflicts and I'm not sure how to resolve them.

Can confirm #13 also works for me.

Re: Kernel >=5.9 breaks bluetooth mouse connection

I could not get e1d572357599d142df5764b39731b6eb55a22beb to revert cleanly either,  gave up after 4 additional reverts was not enough.
What if you its checkout parent 6540351e6f27ef718e3cf5b46349633f3ec57859 or bisect between 5.8 and 5.9?

Re: Kernel >=5.9 breaks bluetooth mouse connection

Hey guys, I am on 5.4.72-1-lts I also experiencing something similar thought it was just me. Basically my newer bose 700 headset wont pair or connect properly. I am also seeing this "Key file" message in the systemd status. I initially thought my problem might be related to group permissions with the LP group so i followed these instructions and edited some configs https://gist.github.com/yejun/2c1a070a8 … 8a998b5495 Weirdly enough the headphones paired briefly but then the sound quality was muddy and then it just got disconnected immediately. I actually dont know what i did but for one reason or another the bluetooth randomly pairs then disconnects. The weird part was that the headphones paired the first time I tried as well, and also the first time I tried connecting as root with bluetoothctl. Its like it trusts new devices then untrusts them, at least thats what I observed. PS. someone smart please lemme know if I should change my settings back I think i may have I think i may have overdone it trying to fix this.

I tried connecting from bluetoothctl while I checked out btmon and I see this "Host is down error" when I try and connect.

Bluetoothctl console

Re: Kernel >=5.9 breaks bluetooth mouse connection

I think your problem is the same as #6, hence also unrelated to this thread.

Hey guys, I am on 5.4.72-1-lts I also experiencing something similar thought it was just me. Basically my newer bose 700 headset wont pair or connect properly. I am also seeing this "Key file" message in the systemd status.

Re: Kernel >=5.9 breaks bluetooth mouse connection
