Lubuntu 16.04.03 Échec d'amorçage avec 4.13
J'ai récemment mis à jour le noyau HW sur Lubuntu 16.04.03, qui installe 4.13.0-26. Au redémarrage, le message "Chargement du disque virtuel initial ..." s'affiche, puis redémarre immédiatement.
J'ai supprimé quiet et splash, et j'ai essayé d'ajouter nomodeset, debug etearlyprintk=vga (séparément et ensemble). Contrairement à plusieurs des autres cas que j'ai trouvés en ligne, le mien ne gèle pas à ce stade, mais effectue un redémarrage. Je peux démarrer avec succès avec 4.10.0-42.
J'ai aussi essayé de réinstaller le noyau avec Sudo apt install --reinstall linux-image-generic-hwe-16.04, et aucun changement.
Je ne sais pas comment obtenir plus d'informations pour déterminer la cause première de l'échec de démarrage. J'exécute une installation de Vanilla sans pilotes spéciaux sur un Dell Optiplex 960. Pas d'EFI, mais le démarrage du BIOS.
J'ai réussi à obtenir une capture de la console série:

Des conseils sur le débogage ou quel est le problème?
Cela semble être un problème dans l'ACPI. À partir du gestionnaire de bogues du noyau Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742675
Et la ligne principale du noyau (mentionnée ci-dessus):
https://bugzilla.kernel.org/show_bug.cgi?id=19814
L'ajout de acpi=off à la ligne de commande du noyau résout le problème.
