Laptop = System76 Lemur6, 8 ram, 120 SSD.
Installed fresh Manjaro w/kernel 4.19.Bluetooth was working fine. Turned laptop off and next morning enabled BT, but it did not work. Queried for adapter and none found.
I upgraded, then to 4.20, but no change.
Loaded running 14.4 kernel and everything is fine.
Are there BT bugs with these 2 kernels?
