primarily because (I could be wrong) suspend/resume is instrumented via
systemd (and systemd-sleep) in particular.  And I felt that there is
some (incorrect) interaction between all the components (systemd-sleep,
systemd-logind) participating in the game.  I do not spot any explicit
message from gdm in the logs which would hint that it behaves
unexpectedly.  It feels more like some powers from above (systemd)
instruct it to restart or smth like that.

but I could be totally wrong... please advise

Indeed.  I mentioned those as just additional symptoms for the main
problem with hope they could help to troubleshoot.
