Mi sistema Debian 9 se activa en 2-5 segundos después de que ingresa al modo de suspensión (suspensión a RAM) manual o automáticamente. El problema siempre ocurre sin importar cómo se invoque el modo de suspensión: al cerrar la tapa, con el botón de encendido o desde el terminal. ¿Cual podría ser el problema?
Aquí está la información del sistema:
$ sudo dmidecode | grep -A3 '^System Information'
System Information

Para verificar qué dispositivos podrían causar un problema, verifiqué /proc/acpi/wakeupy luego deshabilité todos los dispositivos temporalmente emitiendo echo DeviceName > /proc/acpi/wakeup, pero el problema aún persiste. Aquí está antes de cambiar:

Si eso funciona bien, intente encontrar el punto que lo rompe: por ejemplo,acpidinteractuando consystemd-logind(iniciar consystemd.unit=rescue.target), con su administrador de pantalla (iniciar consystemd.unit=multi-user.target) o con su administrador de energía de escritorio (cierre su entorno de escritorio).Respuestas:
No sé si alguna vez resolvió este problema, pero sucedió lo mismo en Debian buster / sid en un ThinkPad T460. El resultado de mi
dmesgno era idéntico al tuyo, pero lo más importante, tenía el mismolínea. Según este hilo en AskUbuntu , deshabilité XHCI como activador de activación en
/proc/acpi/wakeup:y eso me lo arregló. Curiosamente, se suponía que esto solo importaba si tenía dispositivos USB conectados a la máquina, pero ciertamente no lo hice.
EDITAR: No importa, olvidé la parte donde intentaste deshabilitar cada línea
/proc/acpi/wakeup.fuente
XHCestaba causando el problema (ThinkPad T470s, Ubuntu 16.04, kernel 4.15).Problema resuelto. Era de alguna manera el teclado. Una de mis teclas F estaba rota y decidí probar si esta tecla enviaba información constantemente. Luego probé las entradas del teclado en el terminal; no se mostró ninguna entrada cuando no toco el teclado. Aunque ese fue el caso, cuando reemplacé el teclado por uno nuevo, pude poner la PC en suspensión. Supongo que puede ser algo relacionado con Thinkpad BIOS, porque no importa lo que intenté en el sistema operativo, no pude ver ninguna entrada de teclado que pudiera despertarlo del modo de suspensión.
