** Description changed:
+ UPDATE
+ ======
+
+ I tried another kernel (`5.4.0-40-generic` and it didn't worked.
+ Trying to reboot (and get back to the latest kernel) it didn't shutdown, so I
hard shutdown it, and restart with the `5.4.0-42-generic`.
+
+ And now, it works.
+ I hope the logs below may help you to find out what happened, and help others
to fix their issue if it's similar to this one.

Hello,
For now, everything worked fine, until this morning when Bluetooth stop
working.
Ubuntu 20.04
**What expected to happen :** Bluetooth turn on on start, and if it's
off it turns on when I turn it on.
**What happens :** it doesn't turn on.
```
