Eu tenho um Dell XPS 15 9550 . Estou executando o Ubuntu 16.10 nele há quatro meses, sem dramas.
Dois dias atrás, atualizei para o Ubuntu 17.04 . Cerca de uma hora após a atualização, meu disco rígido voltou ao modo somente leitura. Quando pulei para uma tela tty, isso apareceu:

Reiniciei e continuei a obter o erro uma vez por hora. Então eu reinstalei o Ubuntu 17.04 a partir do zero . No entanto, ainda estou recebendo o mesmo problema.
Tentei executar o fsck criando um arquivo / forcefsck (criei um script shell do wrapper que adiciona o -v
sinalizador e gera stdout a um arquivo). Aqui está o resultado:
fsck.fat 4.0 (2016-05-06)

Tentei inicializar a partir de um USB ativo e executando e2fsck -p /dev/nvme0n1p7
como sugerido aqui ( /ubuntu//a/768813/679041 ). Não deu nenhum erro.
Também tentei executar, smartctl -t long /dev/nvme0n1p7
no entanto, os resultados parecem indicar que a ferramenta não funciona com meu SSD específico:

Alguma idéia de por que esse problema pode estar ocorrendo e como posso resolvê-lo? Obrigado! :)
