kernel installed, exactly same problem (cf screenshot from post #54),
the only way to start is still with pci=noacpi
I don't know how to make an acpi dump, I made one but seems in hex,
something unreadable -> https://paste.ubuntu.com/p/z37K3QTQwZ/

Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't

Notebook: Acer Aspire A315
This is a brand new notebook on the market with Ryzen 5/Radeon.
The default kernel of Ubuntu(18.04) hangs at loading with message:
tsc: Refined TSC clocksource calibration: 1996.250 MHz
clocksource: tsc: mask: 0xffffffffffffffff max_cycles: (...), max_idle_ns:
Using pci=noacpi kernel parameter kernel loads without any problem but
my notebook produces more heat than on Win10. If I know right Acer
notebooks need ACPI to the correct power management.
The same thing happens on mainline 4.17,4.18rc1-2.
BIOS upgrade to the latest version: 1.08 hasn't helped
This problem has been reported upstream:
The latest correctly working kernel was 4.13.* but the heat problem
was present with this too.
