For info, I find that subject: https://superuser.com/a/1451102

So I tried to disable bluetooth in bios, boot, re-enable bluetooth in bios.

With that, I was able to "unblock" the bluetooth adaptater in rfkill. 


But I still didn't have any controler listed in `bluethoothctl list`. 


I then tried to disable laptot battery ("power > servicing" option in bios) to
see if a full cold restart does something. 
It does: I've came back to the initial state, where the controler can't be
enabled at all. 
I tried the disable-then-enable-bluetooth-in-bios trick, but that time it
doesn't do anything. 

I also notice than early in boot, I have that message:

---
kernel: usb usb1-port3: connect-debounce failed
---

Which seems to be link to the bluetooth controler (I don't have the message
when bluetooth is disabled in bios).

So it looks like an hardware problem right?
