This depends on your upgrade path of your Mageia install. Is it a fresh
install?

Runlevel 3 works fine here, but if you've upgraded your box from
cauldron for a while, they it's possible that the static getty on tty1
is not configured.

Switch to tty2 after booting to runlevel 3. It should let you log in.

Then make sure to run "systemctl enable getty at .service" to ensure your
tty1 is enabled.

Don't know about that chipset in particular tho'.
