4.13.3-1 kernel - bluetooth does not work

Hello,
I have already posted a bug here but I wonder if somebody has already solved it.
After recent upgrade to linux-4.13.3-1 with some dependencies my bluetooth has stopped working properly. The effect is that after few seconds after starting bluetooth.service (or restarting) I am able to connect my A2DP Headphones but the sound does not come out. Instead after those few seconds my headphones disconnect and I am not able to connect them till I restart bluetooth service. From journal I can provide those logs:

kernel: Bluetooth: Failed to disable LE scan: status 0x0c
bluetoothd[455]: Control: Refusing unexpected connect
bluetoothd[455]: Suspend: Connection timed out (110)
bluetoothd[455]: Suspend: Connection timed out (110)
bluetoothd[455]: Abort: Connection timed out (110)
bluetoothd[455]: Unable to get io data for Headset Voice gateway: getpeername: Transport endpoint is not connected (107)

Downgrading linux to 4.12.13-1 and bluetooth comes back to work again and no errors or warnings appear in journal.
My bluetooth dongle is

03:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

Does anybody have the same issues?

Re: 4.13.3-1 kernel - bluetooth does not work

So, is it a kernel or bluez bug?

Re: 4.13.3-1 kernel - bluetooth does not work

Can you get a more complete dmesg? Do you get similar errors like in https://bbs.archlinux.org/viewtopic.php?id=230362 ? Does the same parameter help?

Re: 4.13.3-1 kernel - bluetooth does not work

Setting the kernel parameter to intel_iommu=off as advised in post attached by @V1del didn't help me with bluetooth issues. Still experiencing the same problems.

Re: 4.13.3-1 kernel - bluetooth does not work

Currently adding bt_coex_active=0 to the iwlwifi module solves this issue temporary.

Re: 4.13.3-1 kernel - bluetooth does not work

I noticed today it stopped working for me with the same error. but I have an orico usb BT dongle

Bus 001 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Device Descriptor:

  iSerial                 0 
  bNumConfigurations      1

Downgrading the kernel didn't work for me

EDIT: got it working by removing the BT device. Audio works fine,  but according to gnome bluetooth GUI is an unknown device, before it was detected as a headset

Re: 4.13.3-1 kernel - bluetooth does not work

I can verify that I had the same issue and that the workaround of bt_coex_active works.

Anyone experienced any WiFi performance degradation after disabling this option? It would be a bummer if I had to choose between network or keyboard...

WiFi Performance ok, music via BT stutters while WiFi generates traffic (dl/updates).
4.13.5-1-ARCH.

Re: 4.13.3-1 kernel - bluetooth does not work

On a Clevo P775DMG3 the Bluetooth didnt work after the normal logging in KDE.

Tried changing device class in /etc/bluetooth/main.conf as following:
# Default device class. Only the major and minor device class bits are
# considered.
#Class = 0x000100 (from default config)
Class = 0x100100

For me it seems enough restart the Bluetooth service for make it work again.
Ill add a script for any startup for not do it manually every time.

Re: 4.13.3-1 kernel - bluetooth does not work

For now the only solution seems to be to disable bt_coex_active.

But there are upstream bug reports already:
