@Giuseppe Di Resta You must verify Armbian build logs in output/debug if I remember correctly. Probably some patches are incompatible with the newer kernel you are using. You can manually force kernel to 5.15.24 or adjust/remove the incompatible ones. Patches related to DTB / DTS are usually critically important for the stable behavior. Unfortunately Kernel 5.17 (some may be back-ported to newer 5.15.x at this time) brings many breaking changes to these options and it would require to completely rework them and test them a lot.
