This is a valuable observation. I presume that these CPUs are too old
to be multicore, best they could have it hyperthreading. Harry, can you
please share the contents of /proc/cpuinfo?

Jeff, could you please try booting with parameter max_cpus=1? I wonder
if it would make a difference. If it does, that would confirm your
theory.

I've seen this nug hit an openSUSE user (on a laptop with one
multi-core CPU), so it's definitely not specific to Fedora. It may be
related to the version of gcc used by the distribution though. If
Fedora people aren't interested, we may open a bug on
bugzilla.kernel.org instead.

I'm glad you like it :)
