J'ai dmesg -Hw qui essaie de résoudre un autre problème (mon ssd passe parfois en mode lecture seule) et j'ai remarqué que cela se produit plusieurs fois par jour, si je m'inquiète

La recherche Google de "[Erreur matérielle]: PROCESSOR 0: 406e3 TIME 1498209621 SOCKET 0 APIC 3 microcode 9e" donne ce qui suit:
Plusieurs choses à essayer:
Installez le microcode. ( askubuntu.com: installation du microcode )
Vérifiez si l'ordinateur est en surchauffe avec lm-sensors
( buntu.com: capteurs, comment faire )
mauvais paramètres irq dans le bios ( erreur matérielle du processeur )
Quelqu'un a mentionné un mauvais bloc d'alimentation et une exception de vérification de machine (mce) pour le disque dur dans le forum Intel ( exception de vérification de machine Linux )
Une surchauffe peut provoquer cette erreur ( surchauffe du calcul du nombre premier )
