Radxa O6/O6N with dietpi

I’m recently playing with my Radxa O6n and it got a good performance!

however, thing get strange when I’m using putty for serial connection, it randomly freeze the terminal and crash into some kind of loop. keyboard input and display are fine before loading up the kernel and go into dietpi itself.

The problem doesn’t exist in official image and in network ssh session.
Does the dietpi installation script touched on the serial-console?

Our Orange Pi 6 image should support it, as they use the same SoC with ACPI boot: Orange Pi 6/6 Plus | Add initial support by MichaIng · Pull Request #8472 · MichaIng/DietPi · GitHub

But whether all hardware features work/are detectes correctly depends on the BIOS firmware.
