I still get freezes when resuming from suspend when using kde and opengl
as a compositor, but this is not related to this issure, or is it?

There is a chance that this also helps with the resume/suspend bug with
kde/plasma. If anyone can test, that would be awesome. I will try myself
as soon as possible.

I found that suspend/hibernate are trouble. But specially KDE/Plasma is
problematic. While Manjaro Plasma refuses to work, Manjaro i3 gives
Suspend (to Disk, assume) out of the box. Everything else so far is
working very good.
Another observation: Monitor flickering occurs when Power is connected
Any experiences with other distributions in the last months? Especially
regarding stability? WLAN and Bluetooth work all the time? USB devices always
show up when you connect them? I could really use some feedback about your
choosen / favorite distribution on this notebook after patch 1.15.
I tested MX Linux for the past weeks and it was stable as a whole, but
WLAN, bluetooth and USB often dissapeared for no reason and forced me to
reboot.

So far it has been quite good. Some report a "slow grub". Sometimes I
have to reboot because no wifi card detected.

Title:
Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs,
Tested Ubuntu 18.04.03 LTS. There were no soft lockups. Only error
messages in journalctl, complaining about ivrs 4 and 5. Also booted a
live iso of MXLinux 18.3 with no issues as well. The new bios update
seems to do .. something.
How to update the BIOS:
Click "DH5JV115.exe" under Winodows mode
Interesting. It does Boot with acpi_osi=Linux, but dmesg/systemctl still
shows complaints about IVRS 4 and 5. Did we already establish some
commands to verify the full functionality of ACPI of this model?

Yes, but did you use systemd or openrc variants of gentoo? And did you
use ~amd64 or stable? I used ~amd64 openrc. With a self-customized
kernel (not the genkernel one). And it worked for a lot of different
kernel versions. I had to tweak stability through kernel parameters like
nomwait=true,
I made the same experience on A315-41 R2GU. But I needed two kernel
options. If I remember correctly it was SME Encryption = No (under
Processor and Features?) and another one, to prevent freezes in one of
the later C-States.

Ok. According to https://wiki.gentoo.org/wiki/AMDGPU disabling SME is
needed for AMDGPU: "Currently, amdgpu does not work with AMD Secure
Memory Encryption (SME) enabled, so you need to disable its use either
in the kernel configuration or on the kernel command line (i.e. in
/etc/default/grub as
It might be interesting that I can boot without pci=noacpi / noapic on
an installation of gentoo/openrc on all recently-ish kernels. Soft
lockups seem to be triggered on almost all distributions while the
systemd service udev hangs. I will test it out, since BIOS update 1.11
did not help any.
