You should restart your computer for systemd

Reboot

System start OK

Query with systemctl status the services I use, looks good

MGA9-64 Plasma Wayland on Compaq H000SB.
No installation issues.
Rebooted after install. All functions I expect (wifi, internet, sound, access to NFS-shares) work OK.

For my curiosity: has the name "systemd" been given/invented by a French person?

MGA9-64, Xfce

Installed and used for a number of hours.  no issues

64bit OK on ASUS Aspire A717

System and test as in Bug 34302 Comment 70 with desktop kernel
linus kernel Bug 34303 Comment 10

Linus kernel fail hibernating (nouveau), OK with desktop kernel, so I assume systemd is not to blame.

I think that's enough testing. Validating.

Yep, while also testing kernels, no issues noted on Thinkpad T43 (i586, LXDE), and 64 bit Plasma on Asus G75V (nvidia470), Thinkpad T510 (nouveau), and my workstation (AMD GPU), all intel CPUs.

An update for this issue has been pushed to the Mageia Updates repository.
