For debug purposes, many assumptions made by the PM developer(s) are checked at run-time. If this event log is seen, it will either indicate that the hardware is in a unknown state that is not handled by the PM, or that a programming bug has been found. For developer debug purposes, the data field describes where in the code that the error was detected. Data Bytes[0-1]: The line number within the source code file where the error was detected. Data Bytes[2-7]: The first 6 characters of the source code file name.
