Bluetooth broken for Intel 9460/9560 on kernel 6.0.7

Hi,
I just build a new computer based on the Asrock B660m-ITX/ac motherboard that uses the "Intel Corp. Bluetooth 9460/9560 Jefferson Peak (JfP)" wireless card as reported by lsusb. After install the Bluetooth does not work however the WiFi works just fine. I tried installing EndeavourOS (arch based) to see if that would have the same issue because I know it ships with a larger set of drivers, including non-free ones, and interestingly Bluetooth worked in the live image but not after it was installed. I tracked this down to the live image using the 5.19.7 kernel instead of the 6.0.7 kernel that is installed to the system. I've reverted back to Arch with the LTS kernel installed (5.15) and it seems to be working ok. The gnome preferences page glitches out on the LTS kernel so I have to use blueman-manager to connect Bluetooth devices but it works. On the 6.0.7 kernel I've tried just about every solution I could find to fix this issue. The Bluetooth service is up and running according to systemctl, rfkill shows the Bluetooth device hci0 as unblocked, I've unloaded and reloaded the kernel module as some people have suggested as well. As far as I can tell, this seems like an issue that's out of my hands and needs to be fixed in the kernel, but I thought I'd post on here just to see if anyone had any ideas.

Re: Bluetooth broken for Intel 9460/9560 on kernel 6.0.7

You can try this scripts:

bton:
#!/bin/bash
sudo rfkill unblock bluetooth
sudo systemctl start bluetooth
sleep 1
bluetoothctl power on
exit 0

btoff:
#!/bin/bash
bluetoothctl power off
sudo systemctl stop bluetooth
sudo rfkill block bluetooth
exit 0

btrestart:
#!/bin/bash
bluetoothctl power off
sudo systemctl stop bluetooth
sudo rfkill block bluetooth
sudo rfkill unblock bluetooth
sudo systemctl start bluetooth
sleep 1
bluetoothctl power on
exit 0

Re: Bluetooth broken for Intel 9460/9560 on kernel 6.0.7

Unfortunately my brand new Silicon Power SSD died last night after 2 days of use. (Lesson learned: don’t cheap out on storage.) So I won’t be able to run those scripts until I get my system back up, but I’ve run each of those commands to no avail previously so I’m pretty sure the issue must be elsewhere. When I tried to do “bluetoothctl power on”, I was getting “No default controller available” in the 6.0.7 kernel.

ok,  +1

Not only 6.0.7, I tried 6.0.2, 6.0.5 and 6.0.6,
all of them could not drive this model of Bluetooth device,
I am using version 5.19.15,now,  this is no problem,
very doubtful that since version 6.0, there are some changes that cause this device to not work.

It was once suspected to be a secure boot issue,
but the btusb module is apparently already loaded, and there are no problems with the same environment in 5.19.

Same here. Intel Bluetooth has not being working since the upgrade to kernel 6.x.

Re: Bluetooth broken for Intel 9460/9560 on kernel 6.0.7

Try this...

- Be sure Windows' Fast Boot is disabled:

cmd > powercfg /hibernate off

- Shutdown the computer, boot directly into Arch, and go with:

# systemctl stop bluetooth.service

###remove bluetooth's modules###
# modprobe -r moduleA moduleB moduleC ... 

###re-insert bluetooth's modules###
# modprobe ... moduleC moduleB moduleA

# systemctl start bluetooth.service

###check if Bluetooth is then working, there's NO need to reboot the computer!###
