https://bugzilla.kernel.org/show_bug.cgi?id=198303 Bug ID: 198303 Summary: Bluetooth dies after a while. Product: Drivers Version: 2.5 Kernel Version: 4.14.9 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: mika.noren@xxxxxxxxx Regression: No Created attachment 273335 --> https://bugzilla.kernel.org/attachment.cgi?id=273335&action=edit journalctl -b -u bluetooth.service Description: Bluetooth suddenly stops working after some (arbitrary?) time. Restarting the systemd service does not help. If one reload the btusb kernel module, one can resume the bluetooth functionality. This has to be repeated quite often during a session. Sometimes with only a few seconds between the failures. Other times it can go several hours without any failure. Additional info: Distribution: Arch Linux Kernel: linux-4.14.9-1 Additional packages: * systemd 236.0-2 * bluez 5.47-4 Steps to reproduce: 1. Boot normally. Enable and pair a bluetooth device. Use it as intended. 2. After some time (seems arbitrary), the bluetooth suddenly stops working. No messages about disconnection or anything. It just silently stops working. 3. "systemctl restart bluetooth.service" does not help. Generates errors as seen in the log attachment below 4. "rmmod btusb && modprobe btusb && systemctl restart bluetooth.service" helps to recover the bluetooth functionality. -- You are receiving this mail because: You are the assignee for the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
