Output of "sudo dmesg | grep Bluetooth", piped into a logfile

Starting with kernel 7.0.7, my laptop's Mediatek mt7922 Bluetooth module
(VID:0489, PID:e0f6) has stopped working. The hardware itself is functional if
I boot on an older kernel, and the actual Bluetooth software stack seems fully
functional, but on 7.0.7 any attempt to connect an already paired device fails,
with bluetoothctl reporting "No default controller available".

I have attached the output of "sudo dmesg | grep Bluetooth" from a boot on
7.0.7.
