Avez-vous observ\u00e9 des probl\u00e8mes avec vos ordinateurs depuis la patch pour corriger "Meltdown" et "Spectre"?<\/p>\n

J’\u00e9tais sur le point d’ouvrir mon PC pour aller v\u00e9rifier les connections aux barettes de RAM, les connections au SSD, de v\u00e9rifier le heat sink de mon CPU, etc, car j’ai plusieurs probl\u00e8mes de ce genre:<\/p>\n

J’ai aussi des I\/O errors avec mon SSD. Intermittents, mais mon petit doigt me dit que c’est le processeur qui essaye de lire un mauvais num\u00e9ro de block apr\u00e8s une erreur au niveau du processeur\/kernel (Je n’ai pas le message d’erreur parce que lorsque \u00e7a arrive le PC est essentiellement inutilisable \u00e9tant donn\u00e9 que mon "\/" est sur le SSD). Je paraphrase l’erreur que j’ai pris en note sur une feuille de papier: blk_update_request: I\/O error, dev \/dev\/sda, sector 446257488.<\/p>\n

Les deux erreurs **semblent**<\/b> arriver en m\u00eame temps.<\/p>\n

J’ai trouv\u00e9 le bug report suivant:
Bug 1532216 \u2013 Machine checks with recent intel microcode
https:\/\/bugzilla.redhat.com\/show_bug.cgi?id=1532216<\/a><\/p>\n

Pouvez-vous s.v.p. v\u00e9rifier ceci sur vos PCs?
# journalctl | grep -i mcelog<\/p>\n

Merci<\/p>\n
