That's a really slippery slope.  There are absolutely low-level firmware areas
that aren't expecting an S3 flow that you're going to trip over.  I /suspect/
this issue you raise is one of them.

Can you please run it as root?  There are checks that require root that I'm
looking for.

Is this the latest for your system?  Please check.


In your two logs I see this.

In order to explain this I need /sys/power/pm_debug_messages to be set and see
the logs associated with it.  Running that script as root should do a full
attempt and set /sys/power/pm_debug_messages or you can manually do this and
share the related dmesg nearby.

After that attempt it looks like there is a series of failure to recover for
your system.
