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.
