Quando eu uso o comando abaixo rctwake, recebo o seguinte erro:
rtcwake -m disk -s 120
rtcwake: assuming RTC uses UTC ...
rtcwake: wakeup from "disk" using /dev/rtc0 at Tue Oct 10 16:27:29 2017
rtcwake: write error
No entanto, quando eu uso a opção "mem", funciona bem:
rtcwake -m mem -s 120
Isso significa que a minha máquina não suporta estado ACP4 S4 (Suspender para disco) ?
Aqui está o resultado do comando: dmesg | grep -i acpi
