Hey guys,
I would like to inform you that I have been inactive for the last few days and will be for a long time due to personal issues. The ARPL will be stalled for the time being.
I believe this server uses a HBA card. DSM Devicetree models do not works with HBA card, only native SATA controllers.
Try change LKM version (advanced menu) from DEV to PROD.
Synology changed the files for 42218 release. Now this release have update6 embedded. Try with this image:

PS: Try with 42962 release and add "codecpatch" addon.
