Patching USB to include your loader. Loader found in 2-2 port
Converting dts file : ds920p.dts to dtb file : >ds920p.dtb
dtb extension is not loaded and its required for DSM to find disks on ds920p_426 61
Copy of the DTB file ds920p.dtb to was not succesfull.
Please remember to replace the dtb extension model file ...
execute manually : cp ds920p.dtb and re-run
