New: Intel Bluetooth 8260 breaks with latest firmware

https://bugzilla.kernel.org/show_bug.cgi?id=190831

            Bug ID: 190831
           Summary: Intel Bluetooth 8260 breaks with latest firmware
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.8.14
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Bluetooth
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

My Bluetooth mouse only works for a few seconds (the exact time appears random) after the Bluetooth controller is reset. At first, it seems only its "frame rate" is reduced drastically, then it completely stops working. It also makes pairing nearly impossible. "hciconfig hci0 reset" briefly gets the mouse working again.

Firmware revision "0.0 build 95 week 37 2016" from linux-firmware 91ddce4 (built 2016-12-05) is broken. The driver boots with these messages:

Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014
Bluetooth: hci0: Device revision is 5
Bluetooth: hci0: Secure boot is enabled
Bluetooth: hci0: OTP lock is enabled
Bluetooth: hci0: API lock is enabled
Bluetooth: hci0: Debug lock is disabled
Bluetooth: hci0: Minimum firmware build 1 week 10 2014
Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
Bluetooth: hci0: Waiting for firmware download to complete
Bluetooth: hci0: Firmware loaded in 1474407 usecs
Bluetooth: hci0: Waiting for device to boot
Bluetooth: hci0: Device booted in 10684 usecs
Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc
Bluetooth: hci0: Failed to send Intel_Write_DDC (-22)

Firmware revision "0.0 build 30 week 18 2016" from linux-firmware 9c71af9 (built 2016-10-05) works fine. The driver boots with these messages:

Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014
Bluetooth: hci0: Device revision is 5
Bluetooth: hci0: Secure boot is enabled
Bluetooth: hci0: OTP lock is enabled
Bluetooth: hci0: API lock is enabled
Bluetooth: hci0: Debug lock is disabled
Bluetooth: hci0: Minimum firmware build 1 week 10 2014
Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
Bluetooth: hci0: Waiting for firmware download to complete
Bluetooth: hci0: Firmware loaded in 1555030 usecs
Bluetooth: hci0: Waiting for device to boot
Bluetooth: hci0: Device booted in 16567 usecs
Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc
Bluetooth: hci0: Applying Intel DDC parameters completed
Bluetooth: hci0: Setting Intel event mask failed (-16)

This problem seemed similar to
https://bugzilla.kernel.org/show_bug.cgi?id=189641 but the loss of function doesn't correlate with any messages. However, while it is broken I do see the occasional repeat of

Bluetooth: hci0 command 0x200c tx timeout

with varying command numbers.

As an aside, it appears the driver will only print the version if a firmware is already loaded. This is a bit irritating as after a complete power-off (to clear the firmware) btusb has to be unloaded and reloaded in order to print the version.

Kernel is linux-zen 4.8.14 x86_64.

Hardware:
Intel Wireless 8260
Logitech MX Master

New firmware with old DDC indeed works. The "Setting Intel event mask failed" message seen with the old firmware didn't reappear, either.

--- Comment #3 from Jan Steffens <[email protected]> --- Actually, that combination just got stuck in the "low framerate" state again, but it did not completely stop working. Again, a hciconfig reset restores it to working order only for a few seconds.

With this file it does not work either.

My Device:

I can observe same symptoms as reporter on Precision 5510 with 8260 [8086:24f3] (rev 3a) Bluetooth works with older version of firmware:

2010a4f3942b6df95ed928f92db3d000 ibt-11-5.ddc
2f06625d1cab8e6edb339dc7a0db4e91 ibt-11-5.sfi

With new version my mouse stops a seconds after connection. When I try to mix old sdi and old ddc it seems to works, but the mouse pointer is jumpy as hell and quite hard to use (but as mentioned the event mask error is not apear with mixed versions)

I will try with attached one in a second and see.

Hmm, the #250451 and #250461 looks like current version of .sfi file and older .ddc file.

Anyway just tired with #250481:

873629534cf972411618c6c13aef80f2 ibt-11-5.ddc
413da432ba53076ed31a1dda17a1f43d ibt-11-5.sfi

The .sfi file has same md5 sum as file currently in linux-firmware repository and only .ddc is different. And it loads fine:

Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014
Bluetooth: hci0: Device revision is 5
Bluetooth: hci0: Secure boot is enabled
Bluetooth: hci0: OTP lock is enabled
Bluetooth: hci0: API lock is enabled
Bluetooth: hci0: Debug lock is disabled

Bluetooth: hci0: Device booted in 10720 usecs
Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc
Bluetooth: hci0: Applying Intel DDC parameters completed

I can not see any event mask errors which is nice and for now I had no problem with sudden mouse stops/disconect, but it still feels a bit jumpy and definitely not so smooth as it should be.

(In reply to G Jaya Praveen from comment #34)

Bluetooth and WLAN are stable even if both active data are transmitted, but the mouse is sometimes a bit laggy.

Is it normal that every data transmission via Bluetooth only reaches about 721 kbit/s (Bluetooth 1.2)?

I'm having similar issue with Bluetooth, but with Microsoft Surface Ergonomic
keyboard. I've posted problem description here:
https://ask.fedoraproject.org/en/question/100782/fedora-25-bluetooth-keyboard-hangs-bluetooth-stack/

If it's broken only in latest linux-firmware, downgrading should fix this
particular issue, right? Because for me it's not.

--- Comment #37 from Robert E. Yawn <[email protected]> --- I see this issue when using my bluetooth mouse (MS Arc Touch).

Not everyone is mentioning the devices that they are using. Note that the MS Arc Touch and MS Surface Ergonomic Keyboard (as reported by Gurenko Alex) are both BT 4.0 devices.

My Logitech K810, a BT 3.0 device, works fine when it is the only device connected. It is only when the BT 4.0 device is connected that these issues are occurring.

Yes, I probably should've mentioned, that my Bose QuiteComfort 35 still works
just fine, although I cannot find which bluetooth version it utilizes.
I've had to reinstall my Fedora 25 KDE yesterday and it again worked just fine
until I've upgraded all packages and even then it worked one session until the first reboot with new firmware.

It's possible that the issue maybe cropping up with certain hardware combos, too. For example, I'm running Dell Precision Workstation 5510. It uses the Int 8260 wifi/BT 4.1 combo with a Skylake CPU.

Same problem here.
Laptop Dell 7559 i7-6700HQ (upgraded with Intel 8260) and mouse Microsoft Designer (Bluetooth 4.0).

Addendum - If i turn off and on the bluetooth leaving the wifi off, the mouse works with no problems. If i turn on the wifi and i connect to a wifi network (2.4G or 5G) the mouse stops working after 5-10 seconds.

We need a fix. :/

- logitech mx master

Case: mouse stops working after 1-2 minutes of active work. When i need to reconnect it to laptop with bluetooth settings, after that mouse also works about 1-2 minutes and drop the connection. With unifying receiver it works fine.

Second:
- Zotac id83 plus
- kernel 4.4
- logitech mx master (the same)

Case: mouse stops working after 5-10 seconds of active work, if wifi is turned off it works fine, but then wifi in ON its stop working. With unifying receiver it works fine.

I've got a similar problem with Debian kernel 4.9.6-3, except my mouse, a Microsoft 3600, just seems to stop, without going into a low framerate first. However, it did seem to go into a low framerate when I tried to see if my BT speaker would work. The speaker would connect, but either not become available in sound settings, or attempting to play to it caused the player (mpv) to just pause at 00:00 indefinitely.

When trying to open GNOME's bluetooth settings when the mouse has stopped working, there's a delay of several seconds before it appears, and I see this in journalctl:

Feb 18 19:29:31 lenny bluetoothd[1140]: Failed to set mode: Failed (0x03)

When the settings dialog eventually opens, it says the mouse is still Connected. Turning bluetooth off and on again makes the mouse reconnect, but only for a few seconds.

disable NetworkManager, bluetoothctl pair device

Lenovo Thinkpad T460p
debian stretch (i used Arch Linux with latest kernel 2017-02-15, same issue) kernel 4.9
Plasma for desktop env
Intel dual band wireless 8260

Checked dmesg:

First connection will keep for few minutes after it will lost connection. When you check plasma Bluetooth-applet, it shows device is connected however, when you try to disconnect device, it will keep showing connected unless you disable Bluetooth,
It will automatically connect your mouse when you enable Bluetooth.

FWIW... I still had the Debian package firmware-iwlwifi version 20160824-1 available in my cache so I installed that. With this version the situation is much improved, but still not perfect. Every so often (something like a couple of minutes) the mouse stops working for a few seconds, then the bluetooth icon in the status bar briefly flashes off, then the mouse connection is restored.

--- Comment #50 from Emmanuel Grumbach ([email protected]) --- OK, we have a wifi BT coex issue here. Taking this bug to wifi.

Pease be more precise with wifi firmware versions. Are we talking about -22.ucode versus -19.ucode?
