Your problem, on wakeup, is logged here:

That is the suspend.....
"Change power state to D0" is waking up.

The suspend problem itself is not logged, because it mentions a problem going to D0, not to D3.
...which is the odd thing, as suspend was at 18:46
Yes, but there is a moment during the suspend process when the hard disk is "stopped" and nothing more can be written to it, and after that is when the kernel does the actual suspend work.
Any log entries done in that interval are stored in the memory of the syslog process, or the kernel message ring, I don't know for sure, and written when the hard disk is waken up again, so the timestamps for those events are wrong, they write the wake up time.
Ah OK....
I have now disabled tlp, and keep monitoring...
Noticed the issue again today. I have opened https://bugzilla.opensuse.org/show_bug.cgi?id=1194197 for this. Have a good new year! Axel
