Eu vou fazer essa pergunta aqui, já que eu parecia ter perplexo o pessoal do Linux Mint. Eu tenho usado o Linux Mint por um ano e meio. Eu tenho 3 computadores e 2 rodam no Linux. Meu computador principal é uma torre de desktop. Eu mudei meu computador principal para o UbuntuStudio alguns dias atrás, quando me senti frustrado com o Mint 18.2 nele. Mas o problema só diminuiu um pouco e não desapareceu com o UbuntuStudio. E isso é um problema sério.
Os sintomas são que eu não consigo ler ou gravar arquivos de qualquer unidade USB externa sem que o sistema falhe e congele completamente. A unidade pode ser formatada como NTFS, FAT32 ou EXT4. O pior é o ext4. A única saída é um reinício difícil. (Botão Off) Esse problema inclui até cartões de memória FAT32. Eu posso transferir alguns arquivos antes que o sistema congele. Mas arquivos grandes ou uma grande quantidade de arquivos de dados sendo transferidos parecem ser impossíveis.
Esse problema afeta apenas o computador.
O computador:
Os discos rígidos foram desligados. Ele tinha 3 discos rígidos internos para 5 TB de espaço. A unidade principal tinha 1 TB de espaço. Eu substituí todas essas unidades por um único 4 TB. Dirigir. As unidades foram desligadas devido a este problema. (Eu percebi que poderia haver um problema com uma das unidades.) Eu também tenho cerca de 25 TB de armazenamento que eu conecto através de portas USB, incluindo uma torre RAID. Todo o armazenamento extra é formatado como NTFS. Mas as unidades que estavam internas estão sendo lidas através de uma interface externa de disco rígido. não há leitor de cartão de memória embutido neste computador. Eu uso adaptadores USB2 e USB 3 para os cartões de memória.
Ao olhar para os registros, vejo que o PAM tem me assinado e frequentemente. Estou sendo desconectado como 'root' e 'user'. Quando vejo os arquivos sendo transferidos, comece a desacelerar, e se eu olhar no log do Auth, ele mostrará que acabei de sair como usuário.
O seguinte é do log de autenticação e do log do sistema. O primeiro foi copiado e salvo apenas quando o processo de cópia estava diminuindo. O computador congelou um segundo depois. (As outras 2 cópias / colagens de log abaixo são dos registros do dia após uma reinicialização.) Tentei deixá-lo descansar por uma hora para ver se ele poderia se recuperar. Não funcionou.
Este registro foi feito no UbuntuStudio:
