Às vezes, meu PC (Linux Mint 18.1) trava quando tenta entrar em suspensão / suspensão sozinho após inatividade. Quando eu volto para ele, o monitor está em modo de espera, mas o computador ainda está funcionando (os ventiladores e as luzes continuam acesos). Não há resposta do mouse e do teclado; Eu tenho que fazer um hard reset para sair dessa.
Eu não sei quando ou por que esse problema invadiu meu sistema. Pode estar relacionado a um adaptador wifi (TP-Link TL-WDN4800 N900) que instalei há alguns meses.
Eu já tentei resolver os problemas usando diferentes Kernels (4.4.0.93, 4.10.0.33, 4.11.0.14), sem sorte.
Existe um adaptador gráfico ATI, mas eu não mudei nada relacionado a ele e ele estava funcionando antes que o problema aparecesse.
Esta é a última parte de /var/log/syslog antes da máquina congelar:

Alguém sabe como consertar isso?
Alguns aplicativos têm a opção de desativar o modo de hibernação enquanto estão ativos. Por exemplo, o transmission-gtk tem a opção Inhibit hibernation when torrents are active . Tente desmarcá-lo (no meu caso resolveu o problema).
P.S. Arch Linux, AMD Phenom2, etc.
