i'm sorry, but I can't find the reply button on the forum.
In any case, @ebin-dev I don't have any monitor connected do the NAS.
The only stable kernel i found is the 6.1.63 (whith this image Armbian_23.11.1_Helios64_bookworm_current_6.1.63.img.xz).
My third try was ok, because the freeze is random, so sometis it occurs after 5 minutes, so you can configure the system.
Edit: I confirm that kenrel 6.1.63 is stable for me. The 6.1 is an LTS version, why isn't update in armbian?
