poweroff/shutdown panics on risc-v

[Chef vom Dienst]

I have MangoPi Pro, which is a single board computer with a D1 RISC-V cpu. I am using the Nezha image from here: https://cdimage.ubuntu.com/releases/23.10/release/ubuntu-23.10-preinstalled-server-riscv64+nezha.img.xz

This works very well (albeit slow considering the hardware), only thing is that shutdown/poweroff is not working, there's a panic (screenshot attached as photo because I can't get the text). (reboot is working though.)

Basically it's badaddr in machine_halt.

Thanks
