Description:
Bluetooth worked perfectly on 7.0.6 but stopped being recognized in 7.0.7.
bluetoothctl reports "No default controller available."
Hardware:
Laptop Model: ASUS TUF Gaming A14 FA401WV_FA401WV 1.0
Error in dmesg (7.0.7):
Bluetooth: hci0: Failed to send wmt func ctrl (-22)
Steps taken:
Confirmed rfkill is not blocking the device.
Verified 7.0.6 works, 7.0.7 does not.
Performed a hard power cycle (60s power button hold), which did not resolve the
issue on 7.0.7.
