Another thing you can try is add "--debug-flags=Exec" to the run to see if the CPU is actually getting started up and running code. If not, that's your problem. If yes, then you can re-run the checkpoint generating run with "--trace-start" set to match the tick where you dump the checkpoint, then see whether the execution after restarting from the checkpoint matches with the execution in the original run after the checkpoint.
