[Impact]
bluetooth can not be used. With previous ubuntu versions (e.g. xenial and zesty) this headset worked mostly flawless (as good as a bluetooth device can work in linux at least).
Steps to reproduce:
- Connect bluetooth headset
- Wait a few minutes, switch profile
Result:
- The bluetooth device is disconnected and the following traces are printed in dmesg
