Thank you for the suggestion. Unfortunately, it didn't help. Here is a boot log after your fix: bt_boot_fail_after_fix.txt

klipper@transpeed-8k618-t:~/8821au-20210708$ sudo modprobe 8812au modprobe: ERROR: could not insert '8812au': Unknown symbol in module, or unknown parameter (see dmesg) klipper@transpeed-8k618-t:~/8821au-20210708$ sudo dmesg | grep 8812 [ 7.950162] module 8812au: .gnu.linkonce.this_module section size must match the kernel's built struct module size at run time klipper@transpeed-8k618-t:~/8821au-20210708$ dkms status rtl8812au/5.13.6-23, 6.12.11-edge-sunxi64, aarch64: installed rtl8821au/5.12.5.2, 6.12.11-edge-sunxi64, aarch64: installed I've compile a new image with MT7601U, it works. What should I do for rtl8812 to work?

none of these are Armbian images. We do not support 3rd party OS.

FYI latest image for rock 5B+ in downloads section is broken (Armbian_25.5.1_Rock-5b-plus_noble_vendor_6.1.115_gnome_desktop) Wont boot at all, previous 25.2.2 images works fine.
