Is this a regression? i.e. Did you have reboot working fine before installing some updates?

> pivot failed: invalid argument

There may be something wrong with your initramfs. Try regenerating it with "dracut -f".

> Restarting system

This message is printed by the kernel. Reassigning.

Does a forced reboot work?:
  sync && reboot -f

Would changing the kernel's reboot method with the "reboot=..." parameter help? See this comment for possible values:
