Bluetooth doesn't (usually) work on booting [MacBookPro12,1]

Linux mbpr13b 4.13.0-17-generic #20-Ubuntu SMP Mon Nov 6 10:04:08 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Just updated to latest repo kernel.

After reboot, the bluetoothd gets started but not activated.

Restarting does not work (error msg in bluetooth panel: adapter not found - it was there before the reboot).

Required several reboots to fix the issue (i.e. after a reboot I have to reboot several times, click the mouse frantically during boot to get it recognized somewhere during the bootup).

I remember this to have happened two kernels before so I think it is a regression.
