Tempo de inicialização longo Ubuntu 17.04 Devido a auditoria

Question

Ao inicializar minha máquina, o tempo de inicialização é maior que 70 segundos de cada vez. Eu tenho um PC bastante decente (i7, 8GB RAm etc). Foi bem rápido quando inicialmente instalei e comecei a usar o sistema. Infelizmente não consigo imaginar o que causou (ou quando) o tempo de inicialização alterado.

Seguindo o conselho do AskUbuntu, eu corri dmesg . Eu tracei o pico para uma auditoria, mas parece que não consigo encontrar nenhum problema relacionado online.
