I've already contacted Acer support and they give the BS answer "We
don't support Linux". I tell them crappy BIOS doesn't matter whether or
not its windows or Linux. its still crappy bios. I suggested they fix it
upstream and I got the response that they'll send it upstream (I'm sure
they will /sarcasm).
Richard Baka, I attempted that method, because your method didn't
generate the .dsl files. -da flag didn't do anything but print some
output without ever creating any dsl files. I ended up having to
generate the .dsl files one at a time using the -e flag to pull
dependencies for each and generate the .dsl files with external calls.
Unfortunately SSDT14.dsl was making calls for a method that doesn't even
exist.
So
External (_SB_.PCI0.GP18.SATA.TPTS, MethodObj) // Warning: Unknown
method, guessing 1 arguments
External (_SB_.PCI0.GP18.SATA.TWAK, MethodObj) // Warning: Unknown
method, guessing 1 arguments
External (_SB_.PCI0.SATA.TPTS, MethodObj) // Warning: Unknown method,
guessing 1 arguments
External (_SB_.PCI0.SATA.TWAK, MethodObj) // Warning: Unknown method,
guessing 1 arguments
These I couldn't get no matter what I included. So I did some digging in
the dsdt.dsl file. Those Methods(TPTS a.k.a. Prepare to Sleep,TWAK
a.k.a. WAKE) don't even exist under the scope PCI0.GP18.SATA. What does
exist is S0W (which means Sleep Wake Status) PS0 (Power State 0 a.k.a.
Sleep) and PS3 (Power State 3 a.k.a WAKE)
PCI0.SATA Scope doesn't even EXIST! So I just removed any calls and
pointers to it in SSDT14.dsl (a whole 2 calls which were if/then
statements pointing at PCI0.GP18.SATA first...
I'm going to try to build the files now. Is it safe to merge the DSDT
and SSDT files into a single file?

Title:
Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't
load, kernel freeze (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash
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.
