Audio is a lost cause. Bribe an Apple or Cirrus engineer for the datasheet. ;)
The thunderbolt module will oops upon system resume, and subsequently refuse to work until next reboot.
The d3cold state needs to be disabled on the NVME controller for it to wake up.
The Bluetooth UART (/dev/ttyS0) is created and then deleted by udev in early boot. Hack around it by reloading the 8250_dw module, causing it to be re-created.
