#regzbot introduced: v6.13.1..v6.13.2

Distro: Arch Linux 
Kernel: since v6.13.2

The bluetooth adapter would be recognized and the bluetooth worked flawlessly till v6.13.1 , but since the v6.13.2 , the bluetooth adapter doesn't get recognized by the bluetooth service and therefore the bluetooth functionality doesn't work . 

I suspect the bluetooth's driver failing to load at the kernel-level. 

$: bluetoothctl
Agent registered
[bluetoothctl]> list
[bluetoothctl]> devices
No default controller available
[bluetoothctl]>
