Comment 328 for bug 1776563

Hi, same problem on my Laptop, also ACER315.41 but with Ryzen 7 2700U, Ubuntu 18.10, kernel: linux-4.18.0-13
The option pci=noacpi seems unstable, I'm not always able to complete the boot procedure and the graphical interface is not started (Unity or whatever).

As Ovidiu suggests in comment #314 this combination seems to work at best, but slows down the boot of a few seconds:
splash (erase quiet)
ivrs_ioapic[4]=00:14.0
ivrs_ioapic[5]=00:00.2
clocksource=hpet
iommu=on
amd_iommu=on
amdgpu.dc=1

CPU temp below 50°C even for a high load, battery duration seems ok, but I have not measured it. BIOS version 1.09
