Intel Bluetooth stopped working with kernel 6.14

Hello,

After upgrade to kernel 6.14 i have problem with my Bluetoothe device, it shows up but it cannot connect or pair with any device.

My device in inxi (bluetooth emuleted usb, build in pci-e Intel 8265 card)

Bluetooth:
  Device-1: Intel Bluetooth wireless interface driver: btusb type: USB
  Report: btmgmt ID: hci0 state: up address: A0:A4:C5:02:55:2A bt-v: 4.2

I’ve found this on dmesg:

[    8.506085] [    T762] usbcore: registered new interface driver btusb
[    8.510997] [    T106] Bluetooth: hci0: Firmware revision 0.1 build 19 week 44 2021
[    8.520350] [    T106] Bluetooth: hci0: Reading supported features failed (-16)
[    8.520359] [    T106] Bluetooth: hci0: Error reading debug features
[    8.520365] [    T106] Bluetooth: hci0: HCI LE Coded PHY feature bit is set, but its usage is not supported.

I’ve tested it by replacing my intel card to older Realtek RTL8821CE card and on Realtek everything works, also there is no errors in dmesg, so its Intel problem.

Does anybody else have similar problem? Or solution?

Same problem here. You can get it work with

bluetoothctl

as a workaround but you have to do it on every reboot.

I can confirm that, so that is a DE problem, not bluetooth itself

I don‘t think it‘s DE related. I have tested it on Arch, Manjaro and fedora 42, too. On every distro it starts with kernel 6.14 series, so it is related to something in the kernel.
