I couldn't mange to install 5.2.1, too. So I used 5.1 and upgraded to 
5.3 instead. That works fine. You could also get ISO of the 5.3-BETAs 
somewhere. Another thing you could try is doing a 'set 
hw.pci.allow_unsupported_io_range=1' before booting the kernel. This was 
mandatory for my A30p before 5.3.
