Subject: Unable to handle kernel paging request at virtual address ffffffc08058e000

Good morning,

I would like to report a regression that appears to have been
introduced into the linux kernel since v6.9.

My device is currently experiencing a panic booting the kernel/rootfs
from an SD card.

The device is a Powkiddy RGB30 which is a portable handheld gaming
console with a Rockchip RK3566 SoC (arm64).

I have tested a variety of devices from a couple of manufacturers with
the same SoC and they all have the same issue,
I have also tested, 6.12-rc3 and linux-next and the same issue appears present.

A full UART dump can be found here: https://clbin.com/zLZAW
