#70164 — Bug#987116: firmware-iwlwifi: AX20* bluetooth random disconnects

Package: firmware-iwlwifi
Version: 20210315-2
Severity: important

Dear Maintainer,

   * What led up to the situation?
Firmware for intel AX200 and AX201 contains a bug. Installing the firmware causes random disconencts of bluetooth audio devices.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I didn't check if this could be fixed by downgrading, because foudn no packages. Arch users found that it could be solved downgrading to firmware 20201218
   * What was the outcome of this action?
   * What outcome did you expect instead?
The whole situation with logs is discussed here https://bbs.archlinux.org/viewtopic.php?id=263040 (This is from arch, but exactly as in Debian). There is no solution up to now, as far as I know.

This morning I uploaded to unstable the newer 20210427-1

Could you try it out?

I am also getting issues with this hardware but on using the 5GHz wifi. I
think it is related to the same issue. Please find my logs here..
https://linux-hardware.org/?probe=d1e0b6ee58

Including a lot of issues in dmesg..
https://linux-hardware.org/?probe=d1e0b6ee58&log=dmesg

It only just started happening today and I am concerned it might be related
to the package updates I did today which included several bluetooth related
ones..

Upgrade: apt:amd64 (2.2.3, 2.2.4), google-chrome-stable:amd64
(91.0.4472.106-1, 91.0.4472.114-1), *bluetooth:amd64* (5.55-3, 5.55-3.1),

#73949

[Multipart message — attachments visible in raw view] — view raw

Hi everyone,
I'm not so sure if this bug is firmware dependent.

I've two different PCs, in the same chamber, with the same BT adapter (with
intel AX200), and very very close to an LG micro stereo.

The older PC has, in two different partitions, Siduction (a Debian Sid
derivative with KDE) and Debian Bullseye Stable XFCE (+ Blueman) with
latest kernel from backport. Both systems pair very well with stereo: I
have not done prolonged texts, but everything seems to work very well and
only in certain cases, after reboot, I have to delete the BT profile and
recreate it again.

In my main pc, with Gnome, the first time I tried the system paired with
the stereo, but now, every time I try, the pairing works for an instant,
but it stops immediately. It's definitely not a hardware problem, as the
system works fine on Windows.
I also tried to install latest firmware from Sid, but it still gives the
same issue.

In conclusion, I think the problem somehow lies with Gnome. :-(

Best regards and happy holidays to all!
Domenico

[Multipart message — attachments visible in raw view] — view raw

Ehm... I forgot to specify that my main PC, where pairing doesn't work at
all, has Debian Stable Bullseye with Gnome and with latest kernel from
backport (5.14.0-0.bpo.2-amd64 #1 SMP Debian 5.14.9-2~bpo11+1).

Sorry and thank you very much again!

#76224

Hi there, for those that have tried the newer version of the firmware and didn't see any improvements, it turns out that you have to **power-cycle** (not just reboot) the machine after installing the newer firmware package. Some users even recommend pulling the laptop battery and letting it sit for a few minutes:

https://www.reddit.com/r/debian/comments/x0rfwu/psa_fix_for_ax200_random_bluetooth_headset/

I made a request to the Backports folks for the 20210818-1 version to be backported. This is a major bug in the Debian Stable version, so it would be great if it could be updated there too, but I don't know if the Debian Stable policies would allow that.

Backports are not to fix bugs in stable. Issues like this should
be fixed via the normal stable channels if possible and the normal
bugtracker is used to track that.
