I have now built the module with the armbian build framework and then it works.

I tried the lastest version "Armbian_community_25.11.0-trunk.472_Odroidm2_trixie_edge_6.18.0-rc5_minimal.img". But NPU is not mentioned in dmesg. Also, I have this red line. what could be the effect on the system ?

Hi, just to give a maybe final feedback on this topic: Although it is not a really satisfying solution, I decided to switch off the sysrq functionality by setting kernel.sysrq=0 in /etc/sysctl.conf. This was 1 month ago and there were no sysrq events in my logs since then. So for now this is a "good enough" solution for me. Thank you all for your support, I learned again a lot ...

You should check uboot logs if the dtbo is loaded correctly. You can get those using a debug serial console. If you don't know what that is or how to connect: https://debug.armbian.de
