I don't fully understand what you want me to do now. Please clarify.

The logs I attached where made with a v6.0-rc7 kernel containing all patches
you mentioned in comment 14. Including the usleep_range patch.
Does these logs help you?

So I should put the notebook to sleep for one hour, without closing the lid?

OK, I'll do
  sleep 10; systemctl start suspend.target
just before closing the lid.
(then put the notebook into my bag and go home from work)
(using the comment 14 patched kernel)
