Same for my Logitech MX Vertical Mouse and HHKB Professional Hybrid Keyboard with kernel 5.9.1
Offline
I resolved with
sudo pacman -S linux-hardened
Offline
I am using Intel AX200 and Logitech MX Master 2S and since upgrading to 5.9.1 I had to reconnect my mouse after every reboot.
After removing
[IdentityResolvingKey]
Key=CDF...
from
/var/lib/bluetooth/<MAC>/<MAC>/info
and a reboot manual reconnection is not needed anymore. I rebooted twice, the issue looks like its fixed.

This patch fixed the issue.
Forgive my ignorance but that means we have to either compile the kernel including this patch ourselves or wait for a new kernel release?

So this is a little interesting. I have a BR/EDR device that is not working. A set of Aperion Allaire BT speakers. My Bose QC 35's work great still.
In the Aperion device, I see:
SupportedTechnologies=BR/EDR;
...
[LinkKey]
Key=
Seems like a similar issue with 5.9.1 but the opposite. My BLE device works fine. For these speakers, they connect fine, yet when I play sounds, I hear a slight click noise and nothing. Tried almost every fix in this post (except compiling the kernel) and no dice.

It seems the issue is still present in 5.9.2-arch1-1.
In the wiki
is mentioned that a restart of the bluetooth.service should be enough, but for me it didn't work without a reboot.

I'm using the version 5.9.3-arch1-1 and the solution described on Wiki works for me

I have the same issue and applying this patch fixed it. https://git.kernel.org/pub/scm/linux/ke … e27515d2d5

I have a similar issue with Logitech MX Anywhere 2S.
linux-lts 5.4.75-1 and linux-5.9.6 fails to pair with bluetoothctl. However, if I try to connect without pairing, it does connect and ask for pairing (yes/no), typing yes establishes the pairing and connection for about 15 seconds. Then the connection drops.
I did try downgrading to linux-5.8.1 and linux-headers-5.8.1 as well as bluez-5.54-2, bluez-utils-5.54-2, bluez-libs-5.54.2 without any luck.
linux-hardened 5.9.8.a-1 manages to pair and connect in the first shot without any issues. Once pairing and connection established with linux-hardened, I can still use the mouse on linux-lts-5.4.75-1 without any issues.

I upgraded to 5.9.6-arch1-1 and my bluetooth issues above were fixed!

I'm seeing this issue on `5.9.8-arch1-1` with the MX Master 3, anyone else? Should I downgrade to `5.9.6-arch1-1`?
Offline
I was seeing the same problem described on this topic after upgrading my kernel to 5.9.8-arch1-1, downgrading to 5.8.13.arch-1-1 restored my bluetooth sanity Hope they fix this upstream, it looks like we've regressed since it was reported as fixed in 5.9.6.
rjhilgefort, fyi, sounds like you should probably try downgrading as well. Here's the command to downgrade:
pacman -U /var/cache/pacman/pkg/linux-5.8.13.arch1-1-x86_64.pkg.tar.zst

@dencold did the proposed fix https://patchwork.kernel.org/project/bl … intel.com/ not work for you?

Had the same issue with HHKB Hybrid. The keyboard wouldn't reconnect ever and required new pairing every time the laptop suspends or bt connection is lost for any other reason.
The workaround worked for me.
(responding just for "HHKB" to get indexed by search engines, for a long time I was assuming the issue is with the keyboard and was searching for a culprit there)

Is the issue still present using linux 5.9.9.arch1-1? That includes the proposed fix.

Fixed for me in 5.9.9.arch1-1. MX Master 3 connected just fine after reboot.

Works for me in 5.9.10-arch1-1. HHKB Hybrid and Logitech MX Vertical connect after reboot.

I just updated and jumped straight from a 5.8.X to 5.9.10-arch1-1 and bluetooth seems to have stopped working completely for me.
Removing the LinkKey information as proposed by the wiki does nothing. Connection to already paired devices is not possible and I also can not re-pair them.
I tried several times to re-pair a pair of headphones via the gui in KDE and bluetoothctl without success. (One attempt even seemed to crash/restart my plasmashell)
Maybe this is a different problem than the one supposedly fixed in 5.9.8/9-arch1-1?
edit:
Looks like my problem was unrelated. I fixed it by reinstalling some pulseaudio packages und restarting the pulseaudio daemon via pulseaudio -k

Thank you for this! Bluetooth has also stopped working for me completely and I had forgotten that I was using a custom build of pulseaudio-modules-bt-git.
After reinstalling pulseaudio-bluetooth and removing the other, everything was working fine again.
