I can confirm I also have this issue on an ACER Nitro 5 AN515-42-R5GT. Ryzen 2500U + RX560X using latest BIOS available v1.08. I'm forced to boot with noapic whether or not IOMMU is even enabled/disabled using kernel 4.18.10.

Using 4.19.0rc2 I could get by using the GRUB additions:
i8042.nopnp ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt
