Ultimamente, minha máquina de desktop gnu / linux está inicializando lentamente. Você adivinha o que está acontecendo com base nos seguintes registros?
Esta é a saída da execução
$ dmesg -d | cut -d "<" -f2 | sort -nr | head
para obter os 10 primeiros eventos de log ordenados pela opção delta time (-d).
50,148100>] EXT4-fs (sda5): orphan cleanup on readonly fs

Isso é

Finalmente, este é o contexto do mais lento.
