Re : [Résolu] Problème de noyau Linux
Bonsoir,
Pouvez vous faire la manip suivante :
booter sur un des noyaux qui pose problème, puis rebooter sur un noyau qui fonctionne et donner le retour de la commande suivante :
cat /var/log/kern.log | grep -B50 "Linux version" | tail -51

Re : [Résolu] Problème de noyau Linux
Bonjour,
Je ne sais pas pourquoi, le noyau sur lequel je n'arrivais pas à booter n'a plus fonctionné. J'ai alors réinsitallé Ubuntu avec un LiveUSB. Après toutes les MaJ, le problème est réapparu avec le noyau 37.
Du coup pour ne pas prendre de risque, je l'ai désinstallé à la main (le autoremove m'a enlevé également le header hwe), je boote bien sur le 5.4.0.26
Voici le retour de la commande précédente :

Re : [Résolu] Problème de noyau Linux
L'objectif de la manip était de voir où ça bloquait. Tu as modifié ton système et tu as donné le retour d'un boot qui c'est bien passé. Je ne peux rien en faire.
Tu es maintenant bloqué sur un noyau 5.4.0-26 et nous ne pouvons pas savoir ce qui bloque sur les noyaux ultérieurs (sauf les réinstaller). Ne pas mettre à jour son noyau pose à terme des soucis de sécurité informatique.

Bon, du coup j'ia réinstallé le noyau 5.4.0-37 à la main
sudo apt install linux-headers-5.4.0-37

sudo update-grub

Oui, problème résolu : Probablement l'installation du hwe qui posait problème.
Merci à tous pour vos réponses super rapides et précises !!

Re : [Résolu] Problème de noyau Linux

Non, c'est peu probable. Comme je l'ai expliqué dans le post #21, toutes les installations neuves de Ubuntu 20.04 sont équipées "de base" du HWE. Si c'était vraiment une cause de bug, ça se verrait sur le forum ubuntu-fr et ailleurs. Mais ce n'est pas le cas.
