Percebi que meu computador acorda aleatoriamente do modo de suspensão, seja quando eu fecho a tampa ou quando eu o suspendo manualmente no menu do sistema. Isso acontece quando o laptop está funcionando com bateria e quando conectado.
Eu olhei para /var/log/messages e parece que algumas ações suspensas só estão acontecendo depois que o computador acorda - não tenho certeza se algo está acontecendo ou se talvez o registro das mensagens (não as ações em si) foi interrompido pelo sono e depois escrito após o despertar. Diferente do que eu não consigo encontrar um padrão ou razão pela qual o computador está acordando:
