+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'.
