same as my experience with 5.18 kernel except i didn't build armbian from source. thanks for the case @Aapo Tahkola will try it out. i got an rk3228 box running my printer at the moment occasionally testing rk3318 box as well, they both seem fine and on average use very little cpu and ram usage during printing, it seems these boxes can handle 2-3 simultaneous instances of klipper at the same time maybe even 4 with your case design.

Hello again. manual upgrade from 5.15 to 5.18 kernel and dtb works flawlessly. everything works except hdmi. im currently running my h96 max box with board version rk3318_v1.4. my procedure was install armbian with kernel 5.15 using multitool and sd card while plugged in to an hdmi monitor/tv since multitool and 5.15 kernel works with hdmi. after configuring with rk3318-config, i plug it in to lan and continue running the box headless, then i manually upgrade to 5.18 kernel and dtb. config was 1.1GHz, ddr and emmc is option 1 (typical speeds), led conf i used is led-conf1 (YK led conf i think). seems to work fine and stable apart from the hdmi. i have attached dmesg for 5.15 and 5.18 logs if anyone can spot differences. dmesg-5.15-kernel.log dmesg-5.18-kernel.log
