With OCLP Mod 3.xx versions, the amfipass kext no longer has a valid signature.
There is no need to use lilubetaall but -amfipass as bootarg.
However, there may also be other problems.
On AMD we don't have VT-d, so fortunately for us this problem does not exist.
If you also have a Realtek 2.5Gbit network card, you may need to add another block, as mentioned by laobmac on another forum.
