In my Arch Linux installation, I compiled and installed new fr=
esh kernel 4.19.=20
I have non-standard hardware configuration where are: Radeon R7 360 (Bonair=
e),
Radeon RX 480 (Ellesmere) and Radeon RX VEGA 56 (GFX900) graphics card.
If Radeon R7 360 was handled by Radeon driver (not AMDGPU) then system has =
been
started properly without that errors. I solved temporarily trouble by suppl=
ying
kernel parameter 'amdgpu.dc=3D0' (just disable DC). I have connetected moni=
tor to
Intel IGP (in the motherboard DVI port) and I am not using any Radeon graph=
ics
card to display screen.
After run and loading AMDGPU driver module kernel print errors (if all Rade=
on
graphics cards are handled by AMDGPU driver and if no amdgpu.dc=3D0 paramet=
er):
