Bluetooth controller fails to initialise on Dell XPS 13 (9310)

Very rarely it does work, but it’s one out of ten boots at most

I have the exact same behavior. I am on one of these rare boots right now, yet inxi says it doesn’t work. But it does, I am using it atm.

$ inxi -E
Bluetooth: Message: No bluetooth data found.

Is there anything I can do to help further investigation?

System:

$ inxi -SM
