Estou usando um laptop com apenas um eMMC como armazenamento. Estou usando o Lubuntu 17.04
Por algum tempo, meu /var/log/syslog e /var/log/kern.log estão sendo spam de:

Parece ter sido um problema comum no passado, mas não consegui encontrar nada de útil / recente.
Por favor, deixe-me saber se você precisar de mais informações para sugerir uma solução
Eu desisti. Substituiu Lubuntu com o Ubuntu e o problema desapareceu. O único preço que estou pagando é, com um par de janelas do Chrome, thunderbird e uma linha de comando, estou sempre correndo perto de 4G (e meu laptop tem apenas 4G de RAM). Eu posso viver com isso.
