Estou vendo alguns erros estranhos no syslog. Estou executando um debian 7.9. Alguém já viu isso antes e / ou sabe o que pode estar acontecendo? Meu disco rígido está falhando? Eu fiz um fsck outro dia na inicialização e não havia mensagens dizendo isso. É um disco rígido externo criptografado por USB (LUKS), que é descriptografado / montado na inicialização. Não há RAIDs nem nada do tipo configurado no computador. Eu tenho duas outras unidades configuradas da mesma forma, sem problemas.
Olhei para os dados inteligentes da unidade e ela diz que passou no "teste geral de saúde". Há mais alguma coisa que eu possa verificar / fazer para ter uma idéia de sua condição? Por que eu estaria recebendo esses erros?

Também olhei para este site e um dos pôsteres altera seu sysctl.conf como o que está colado abaixo, mas o meu já está definido assim ...
