1. Please describe the problem: After upgrading kernel from 6.11 to 6.12, bluetooth audio has become unreliable. 2. What is the Version-Release number of the kernel: 6.12.9-200.fc41.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Current default kernel of the fresh ISO which is 6.11 seems fine. I can't reproduce it on <= 6.11 kernel. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: - connect bluetooth headphone - start youtube video in the background - open speedtest.net and run speedtest using my wifi connection, then bluetooth audio is completely lost or stutters. Note: My wifi connection is connected to 5GHz network. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Yes. I can reproduce the issue as of `6.13.0-0.rc7.20250114gitc45323b7560e.56.fc42.x86_64`. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Reproducible: Always
Created attachment 2073459 [details] Kernel log
I've been testing every new kernel releases since then and it's currently reproducible on all the kernel versions including vmlinuz-6.13.9-200.fc41.x86_64. I'm not sure if the attached log is going to be enough. But if someone is interested in fixing this bug, I can work with you to troubleshoot and collect the information you'll need. Unfortunately I cannot upgrade my kernel version to anything beyond 6.11.11-300.fc41.x86_64 because of this issue. In case it helps, affected laptop model is: Lenovo Legion 5 Slim with AMD Ryzen 7 8845HS CPU.
