Abaixo estão as principais lacunas do meu dmesg log:

Eu deveria rodar um fsck no SDA6, parece que ele foi mouted somente para leitura. Isso poderia ser um sinal de que encontrou erros. Se você inicializar o ubuntu com sucesso, desmonte o SDA6 se possível e execute um fsck nele. Se você não puder desmontar o SDA6 porque ele está montado em / ou em outro lugar que seja essencial, execute um CD de inicialização para executar o fsck.
