J'ai installé Arch sur un Lenovo Yoga 300 (genre de netbook hybride) et j'ai un problème avec le wifi (carte Intel Corporation Wireless 3160 (rev 93)):
au bout d'une durée aléatoire (entre 5 et 30 minutes), il ne fonctionne plus, l'arrêt/relance du service NetworkManager ne résoud rien.
Lorsque je constate le dysfonctionnement, dmseg me sort des messages d'erreurs concernant iwlwifi dont voici des extraits:
