I've got some interesting news. I did in fact contact Acer Support and opened a case. Went from Lvl1 to Lvl2 support, was called a couple weeks later with a survey about support, I gave my honest opinion, stating that I don't blame support team as they are limited in what they can do. Today I received a call from LVL3 support! They wanted me to go over my problem in more detail. I let them know of the issues with disassembly and the calling of scopes and functions that do not even exist in the firmware, and that they may be doing something in software with windows drivers to hide it or make it work anyway. He did let me know that they do target the Windows 10 audience and couldn't promise anything, but then I mentioned with the way Windows 10 updates are going I doubt Acer is going to continue to rewrite drivers everytime Microsoft breaks them with their updates, and considering how terrible QA is with windows updates lately having it all just built correctly in firmware to begin with would avoid that. The man agreed and laughed a little. I let him know about iasl and asked if he could have the team look into acpi a little better and that I knew they had dealt with linpus in the past which is effectively just fedora, so I know they have some experience with Linux. I also mentioned my model wasn't the only one affected by these oddities and there were threads in ubuntu, fedora, and the linux kernel's bug system. He agreed to pass on the issues and information to the engineering team in Taiwan. Fingers crossed. So far the customer support has blown away Samsung. I'm not holding my breath for a fix, but I am impressed I got this far.
The LVL3 support guy said he'd call me back when he got a response from Taiwan's Engineers. So I'm guessing within a couple weeks. I told him I understood it wouldn't be a quick response, or even a quick fix if they agreed. He was very cordial and the conversation went well at the least. Thumbs up for Acer Customer Support guys. Color me impressed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1776563 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: New Status in Linux: Incomplete Status in linux package in Ubuntu: Triaged Status in linux-firmware package in Ubuntu: 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.
