the driver crashed on load, try to install dsm 6.1.3 (thats the version the source for the drivers is used) also try to use the new 4.8 version (it will contain a frehly compiled version, but i dont think that will fix it, the drivers seemed to be compiled in a way that thea where working, could also be a incompatibility from synology or a general one that was fixed in later kernel versions)
