With bios/UEFI 1.13 and kernel 5.0.7 things seems to work. I got touchpad working by installing https://github.com/Syniurge/i2c-amd-mp2 (master works, the wip-v16 doesn't work and screwed up a lot of things when i tried it so don't try that version).
git clone https://github.com/Syniurge/i2c-amd-mp2.git master mv master i2c-amd-mp2 cd i2c-amd-mp2 LANG=C sudo ./dkms-install.sh First i booted with pci=noacpi and with that touchpad wasn't working with bios 1.13 that uses advanced touchpad, it did work with earlier bios that had basic option for touchpad. Removing pci=acpi and instead using: ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 did the trick for me. I sometimes needs to toogle wifi after suspend, i haven't tried hibernate. My laptop is an A315-41 non G but it think the G only means that it also has a dedicated graphicscard. I haven't tried it out much yet but at least things seems to work now. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
