There _is_ something missing here.  After that last line I would
expect to see a bunch of log entries from an attempt to resume.
A resume part was either not really running at all or failed early
enough before anything had a chance to write in a log.  This seems
to be an information although I am not sure what to do with it.  Do
you see the same if you try to hibernate/thaw?  I would also compare
with pm-suspend.log from when you are running a rawhide kernel which
you say does these things for you

I get exactly the same issue with hibernate/thaw too.

I've compared the log files and with the exception of a couple of modules being absent (lib80211_crypt_tkip, wl[1], lib80211) and a couple of modules being present (fuse, shpchp, intel_ips) there isn't a lot of difference except that the log file above is 'missing' something.  The missing bit is the bit where it resumes properly ;-]

[1] I know that wl is a proprietary driver, but I can assure you that I have tested extensively with it not loaded (and not even loaded at boot up).  I'm aware that this module taints the kernel, but I've got it installed on the kernel that works and it's not causing problems.  I'm happy to supply proof of this bug without wl installed.

It should read like this:
