So to be clear. AT THIS DAY, there is still no fix for the A315-41 (without the G!!).
My config (the best result from all my tests) : - A315-41 Ryzen5 2500U 8 cores 3600mhz - Linux ubuntu 18.04.2 - bios 1.11 configured (I didnt go to 1.13 while it seems worst on A315-41 series...) - 4.20 kernel - ivrs args (rcu_nocbs=0-7 ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2) it's usable with theses conditions (rarely freeze,all is working,11 ACPI tables loaded & few ACPI BIOS Errors in dmesg) but the main problem is the shitty battery drain (since day 1). (1h30 on linux, 3h on windows) even with low cpu usage (I can reach 3200mhz on stress tests): cat /proc/cpuinfo | grep MHz cpu MHz : 1334.217 cpu MHz : 1275.689 cpu MHz : 1282.695 cpu MHz : 1278.429 cpu MHz : 1328.024 cpu MHz : 1300.042 cpu MHz : 1480.938 cpu MHz : 1642.668 I'm using it everyday since months... never far away from my battery charger.... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/amd/+bug/1776563/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
