Compiling any disk adapter modules is not possible at the moment due to unexported syno_libata_get_index function (declared in libata-core). So only way to fix it is recompile kernel (we don't have latest kernel sources to do that) or somehow modify drive adapter sources to not depends on syno_libata_get_index function.
Edit:
Files moved to mega.nz from my webhosting.
Thank you very much for this release. Is it possible that for the next release include support also for ata_piix module. On my bare metal (old IBM Server) the Hard disks are not recognized.
