Which version of Haiku are you testing? Beta 3 or the Beta 4 release candidates?
I have tried both the nightlies and the Beta 4 RC; no dice on either.
There are still some known problems when booting Ryzen based systems using the old style BIOS/MBR bootloader(ticket 16947 for example). I think it’s still required to set up UEFI in order to boot on a Ryzen.
I took a look at the ticket you linked and tried placing the USB as #1 in the boot order; and that did get me closer into the bootup (icons lit up) but the final Installer application never showed.
