Eu tenho um Asus EeeBox PC-B204 (especificações originais aqui: link ) rodando o Ubuntu 14.04.5 LTS; A única coisa que mudou foi o disco rígido original para um SSD Kingston V300;
Até aí tudo bem. Mas ultimamente eu comecei a receber alguns erros, depois de algum tempo o sistema estava entrando em um modo readonly - nem mesmo a conexão através do ssh era possível;
Então eu removi o ssd, conectei-o a outro computador e executei alguns testes de detecção / reparo usando o Hirens Boot CD; Então, a partir do windows usando o Kingston SSD Manager, atualizei o firmware do ssd;
Montei o ssd de volta na minha máquina linux, em 2 dias sem congelamento / alternando para o modo somente leitura, mas recebo muitos desses (a cada 1-2 minutos):

Alguma idéia de como identificar o problema? É meu ssd quebrado? Ou meu controlador sata?
