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

Status in amd:

Confirmed
Bug description:
CPU: Ryzen 5 2500U
VGA: Radeon 535
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:
(...)
Soft lockup
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:
https://bugzilla.kernel.org/show_bug.cgi?id=200087
The latest correctly working kernel was 4.13.* but the heat problem
was present with this too.
