After some more testing I found that these params are enough for me to
boot properly on A315-41G, bios 1.13, ubuntu 18.04, kernel 4.18, uefi,
"mem_encrypt=off ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2
rcu_nocbs=0-7 idle=nomwait acpi_enforce_resources=lax"

Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs,
I haven't been able to boot with no params with 1.13. bios, but now I
can make it work with:
"text radeon.modeset=0 amdgpu.runpm=0 mem_encrypt=off
ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2 rcu_nocbs=0-7 idle=nomwait
With these params everything works fine - gpu,
Yes, I tried:
"text ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2 radeon.modeset=0
"text ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2 clocksource=hpet
iommu=on amd_iommu=on amdgpu.dc=1"
"idle=nomwait iommu=pt amd_iommu=on rcu_nocbs=0-7 pcie-aspm=off
I can't make gpu and suspend work at the same time on Acer A315 41G R6IM
with Ryzen 2500U and Radeon 535.
If I use pci=noacpi gpu works fine, but laptop hangs on suspend, if I
use ivrs_ioapic... suspend works fine but with no 2d gpu acceleration -
everything works sluggish, very high cpu on
