Bluetooth prompt error at startup

coss · 2022-01-13 07:12:49

Prompt the following information when I turn on my PC. But I didn't notice anything unusual when using it.

1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM kernel Bluetooth: hci0: Failed to read codec capabilities (-56)

Finally, what can I do to get rid of the prompt？

I have the same messages, is bluetooth provided by iwlwifi on your system ?

See https://wiki.archlinux.org/title/Silent_boot for methods to silence various things including messages like these

Hi, I use wired network, so I don't have iwlwifi.
This information was only available after I updated the system on the 1/13th.
Current System Version: 5.16.0-arch1-1.

Many wireless chipsets also provide bluetooth, you may have iwlwifi loaded without realising it.

The messages occurred first on my system with kernel 5.16.0 , not with 5.15 kernel .

Please post lspci -k (run as normal user, not sudo or root) so we can verify what chipset / kernel module takes care of bluetooth on your system.

Welcome to archlinux forums.

I'm seeing the same with kernel 5.16.
Relevant kernel.org thread.
Fix in 5.17 tree.

It's commit which caused kernel error:

That's a wifi/bluetooth chipset as I suspected.

The messages are caused by a bug in kernel 5.16.0 , see (the links in ) post #5 and #6 for more info .

Dear Lone_Wolf, I appreciate your responses and overall trying to be helpful. This is my first message in Arch Forum so please inform me if I'm violating any rules.
If the issue is patched in kernel 5.17.0 release, does that means when 5.17.0 version comes to the Arch repositories that error messages will be gone(the messages OP mentioned)?
Thank you in advance.

The same error shows up in 5.16.1:

Here's the WiFi/Bluetooth chipset:

06:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)
Subsystem: Intel Corporation Device 0014
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi, wl

Seems to work OK.

Lone_Wolf · 2022-01-17 12:27:35

kernel 5.17 is at its first Release Candidate , and may not be released as 5.17.x the next 2-3 months .

Kernel maintainers may feel this fix is not important enough to backport it to the 5.16.x kernels .

If someone feels it is important enough, file a bug report in archlinux bugtracker and ask for this commit to be added to the linux package as a patch.

Thank you. As for me it's just little annoyance when logging in. Also I don't use any Bluetooth device, I think I'll just wait.
