One more triaging step I'd recommend is to try an upstream kernel of the
same vintage. If that works, you know that some change Fedora adds is
breaking it. If it doesn't work, you know that Ubuntu and SUSE both have
a patch that Fedora doesn't which fixes it.

(I suspect this may come down to graphics code; Fedora generally carries
rather newer upstream versions of intel, nouveau and radeon than other
distros, and these can introduce regressions).

It's not strange, suspend/resume is critical to most laptop users. It's
just pretty hard to diagnose and fix.
