Je viens de faire une nouvelle installation d'Ubuntu 20.10 sur mon ordinateur portable MSI GE66. Pour une raison quelconque, le Bluetooth bascule rapidement et s'éteint. Voici une vidéo qui montre ce qui se passe : https://youtu.be/Y7kT3Nkxkag
Aussi, quand je lance htop
il montre que systemd-udevd
utilise 100% de mon CPU (un des 16 threads de ma machine). Exécution de udevadm monitor
continue d'imprimer ce qui suit :

Que se passe-t-il exactement ? Comment puis-je résoudre ce problème ?

Edit 2
Même si je n'arrive pas à faire fonctionner le bluetooth, c'est très bien. Je suis d'accord pour le désactiver entièrement, en fin de compte je ne veux pas qu'il consomme le CPU comme il le fait actuellement.
Edit 3
Je viens de faire une nouvelle installation d'Ubuntu 20.04 à la place, j'ai le même problème.
