dmesg

Notebook: Acer A315-41G-*

4.* kernels start only using these parameters:
amdgpu.runpm=0 radeon.modeset=0 or compiled without VGA switcheroo.

lspci and dmesg attached

Even with these parameters significant heating occurs however this can be fixed
by running "sudo echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" command.

It would be the best if both of them worked correctly like on win10.
