[Résolu] ACPI Error: AE_NOT_FOUND

J'ai noté "Résolu" dans le titre parce qu'il y a toujours une bonne âme qui croit que je demande de l'aide. Je préfère éviter.ça.

Depuis que j'ai installé Ubuntu 22.04 dans mon PC ACER Aspire M5100, je vois furtivement au démarrage des lignes "ACPI Error: AE_NOT_FOUND". Je sais que ces lignes sont sans importance (voir ici) mais j'ai voulu savoir ce qu'il en était sur mes autres install de Ubuntu qui sont dans ce même PC ACER. Déjà, j'ai pu vérifier que ces lignes sont visibles dans le fichier /var/log/syslog de mon Ubuntu 22.04.

On note que la ligne LNKA se répète 7 fois, la ligne LNKB se répète 7 fois, idem pour la ligne LNKC et la ligne LNKD. On note aussi une date "20210730" ; je ne sais pas à quoi elle correspond. : ça viendrait de là

Si je démarre sur mon install de Ubuntu 20.04, les lignes "AE_NOT_FOUND" ne s'affichent pas sur l'écran et cependant, on peut voir qu'elles existent dans le fichier syslog.

Là aussi, on note le même phénomène de répétition 7 fois que pour Ubuntu 22.04.
On note aussi une date mystérieuse "20170831" : ça viendrait de là

Conclusion : je ne sais pas pourquoi ces messages avec ACPI Error s'affichent sur l'écran de mon installation de Ubuntu 22.04 alors qu'ils ne s'affchent pas pour mon install de Ubuntu 20.04 ni pour mon install 18.04. Il doit y avoir une mauvaise raison pour cela. L'important, c'est que ces messages n'ont aucune importance.

Re : [Résolu] ACPI Error: AE_NOT_FOUND

olivierm38 a exactement les mêmes lignes que moi dans ce fil : https://forum.ubuntu-fr.org/viewtopic.php?id=2036154
D'après les conclusions du fil, ce serait dû à un Bios trop vieux. Dans le cas de olivierm38, la version du Bios est de 2010 et dans mon cas, c'est encore plus vieux (2007).
Je note que dans le cas de olivierm38, il y a eu affichage des lignes sur l'écran dès Ubuntu 18.04. Alors que dans mon cas, l'affichage sur l'écran ne s'est produit que pour Ubuntu 22.04 (pour 18.04 et 20.04, je n'avais pas ça sur l'écran)
