The command uname returns "unknown" on Fedora 38,39 and probably 40.
There is a similar very old bug here which has not been fixed

Indeed there is, and I merged your bug report into that old one. It'd be
nice if someone could get to the bottom of that bug.

I decided to look into this a bit, since I also have an unknown
'uname -i' and 'uname -p'.
It seems that this option is a Solaris thing. I found the commit that
it was introduced [1]. It also adds some other Solaris compatibility
stuff, so everything seems to add up so far.
The first function it tries is sysinfo (SI_PLATFORM, ...) which seems
to be a Solaris thing [2]. I think Linux has sysinfo but not
SI_PLATFORM.
Then it tries sysctl (...) with a UNAME_HARDWARE_PLATFORM macro to deal
with the BSDs. I think OpenBSD might be missing that definition in the
#ifdef, but I have no way of testing it at the moment [3].
I'm not sure if 'uname -i', 'uname -p', or 'uname -m' are supposed to
be any different from each other. Maybe someone who knows Solaris can
help more?
Illumios defines 'sysinfo' as an alias to 'systeminfo' [4]. There it
returns an 'extern char *platform' in the given buffer when passed
SI_PLATFORM [5]. I've found the definition of the variable, but I
don't know where it is actually set to something useful [6]. Hopefully
that information helps someone...

Thanks for looking at this.
From the Fedora side, they dropped a Fedora specific patch for Fedora 38.

FWIW: OpenSUSE still has that patch which was kept in sync with Fedora for years:
https://build.opensuse.org/projects/openSUSE:Factory/packages/coreutils/files/coreutils-sysinfo.patch?expand=1
I have no strong opinion about it, but I guess some (build?) scripts rely on this.
Have a nice day,
Berny
