btmon & journal logs – cold boot (failure) vs. “systemctl restart bluetooth” (works)
The ZIP archive contains four files to illustrate the difference between
“cold boot → audio stream drops after ~5 s” and
“bluetooth service restart → stream remains stable”:
btmon_boot.snoop
btmon trace after a fresh system boot
journal_boot.txt
journalctl -b from the same session
btmon_after_restart.snoop
btmon trace after sudo systemctl restart bluetooth
journal_after_restart.txt
journalctl immediately after restarting the service
Reproduction steps:
Boot the system normally (bluetooth.service starts automatically).
Pair the Soundcore Q30 and start an audio stream → it drops after ~5 s.
► Logs: btmon_boot.snoop + journal_boot.txt
sudo systemctl restart bluetooth
Reconnect the headset → the stream remains stable.
► Logs: btmon_after_restart.snoop + journal_after_restart.txt
Observation:
In the failure case, the HCI log shows an “Authentication Failure (0x05)”
immediately before the disconnect; this does not occur after the service restart.
System information:
Fedora 42
Kernel: 6.15.5-200.fc42.x86_64
bluez: 5.83-2.fc42 (behavior is identical to 5.83-1.fc42)
Issue is reproducible with Soundcore Liberty Neo as well
The .snoop files can be opened in Wireshark
using the “Bluetooth HCI snoop log” file type.
The issue in bluez-5.83-1.fc42 remains unresolved and was closed prematurely. I have uploaded additional HCI and journal logs that clearly demonstrate the fault—on cold boot the audio stream drops after ~5 s, and only stabilizes after systemctl restart bluetooth. Please reopen this bug for further investigation. FEDORA-2025-e53a11a6d0 (bluez-5.83-2.fc41) has been pushed to the Fedora 41 stable repository. If problem still persists, please make note of it in this bug report. I am experiencing the same problem on Fedora 42 KDE. Affected versions: Kernel: 6.16.4-200.fc42.x86_64 BlueZ: bluez.x86_64 5.80-1.fc42 The only solution I found was to downgrade BlueZ to 6.16.4-200.fc42.x86_64. Sorry, the affected version of BlueZ is bluez.x86_64 5.83-2.fc42 |
