The solution for Acer A315-41G-* notebooks: (USE AT YOUR OWN RISK - PLS be very careful)

1. Load kernel with these parameters: ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 nomodeset
This is how it can be done (1. answer/first half 1-4): https://askubuntu.com/questions/19486/how-do-i-add-a-kernel-boot-parameter

1/b.(if it is not installed) Install ubuntu and load installed kernel again using the parameters (see 1.)

2. Start a terminal and do these steps:
> cd ~
> mkdir kernelbuild
> cd kernelbuild
> wget -c https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.6.tar.xz
> tar -xvf linux-4.17.6.tar.xz
> cd linux-4.17.6
> sudo apt install git build-essential kernel-package fakeroot libncurses5-dev libssl-dev ccache bison flex
> make menuconfig

If you install xsensors (sudo apt install xsensors) and start it (xsensors) you can monitor the temperature values of your notebook. (Recommended)
