Eu tenho uma instalação de testes Debian bastante atual (kernel 4.16.0-2-amd64 ). Há algum tempo, o computador imediatamente reativa depois de executar pm-suspend ou dbus-send --print-reply --system --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.Suspend boolean:true .
dmesg diz o seguinte:

A alteração de todos os dispositivos para disabled em /proc/acpi/wakeup também não altera este comportamento. O que mais eu poderia tentar diagnosticar o problema?
