Hi Matthias, Similar issue was found on some developing projects, but I'm not sure if we're talking about the same ones. The properties you're asking can mostly be directly retrieved from sysfs and kernel messages to avoid interference from upper layers. I'm personally used to enable kernel config CONFIG_SUSPEND_TIME=y to observe how long has the device been sleeping, along with some hard-coded debug flags for tracing suspend interrupt sources.
