J’ai un problème de réseau, j’essai de résumer vite fait.
Ce WE, le 10, voyant qu’une mise à jour du noyaux avait eu lieu, je redémare mon portable (asus UX305F).
— au redémarage, plus de wifi, ordinateur qui « freeze ». Les commandes en sudo bloquent et ne me laissent plus d’autre choix que de fermer le terminal ;
— passer sur ethernet ne donne rien (j’ai une « prise » ethernet branchée en USB qui fonctionne habituellement) ;
— reboot sous windows, wifi et ethernet fonctionnent ;
— reboot avec live usb archlinux, j’ai de l’ethernet avec le chroot ;
— identifiant un problème avec Network Manager, j’inactive NetworkManager, je passe à netctl : le wifi a fonctionné une fois, j’ai de l’ethernet ;
— depuis, si j’essaie de lancer le wifi, le système « freeze » encore, hard reboot obligatoire ;
— l’ethernet fonctionne.
Je me suis aperçu que je n’avais pas redémarré ma machine depuis le 18 février, tout en ayant fait des mises à jour régulières. Du coup difficile de trouver la mise à jour coupable Mais j’ai les logs…
J’ai tenté de downgrade à un kernel plus vieux, sans effets.
Dans mon dmesg, je vois des erreurs liées à iwlwifi (il y a bien eu une mise à jour de linux-firmware récement) :
