Package: bluetooth Version: 5.50-1 Severity: important Dear Maintainer,
Issue: Bluetooth device with multi device connection crashes kernel. It appears that bluetooth on Linux seems to not be able to work with BT devices which support multidevice switching. Environment: - bose sport bluetooth headphones with multi device connection - Thinkpad X1 Extreme Gen 2 Repro steps: - I have bluetooth headphones connected to two devices: 1. Android phone; 2. Computer - Connection is active on the Computer - for example listening to video on youtube. - I take my phone and start listening musing on my phone. The connection switches to the phone. - I noticed that the connection appears connected on Computer too (in KDE Bluetooth device manager). Its not disconnected. - When I want to switch back to computer, it does not work. I cannot hear any audio. I tried many different combinations but nothing works. - When I power the headphones off and back on (trying to reestablish the connection), I get the following kernel issue which crashes my computer.
