Explanations for your system
🚦 Userspace wasn't asleep at least 0:00:30
        The system was programmed to sleep for 0:00:30, but woke up prematurely.
        This typically happens when the system was woken up from a non-timer based source.

        If you didn't intentionally wake it up, then there may be a kernel or firmware bug
