With 2 monitors (one on VGA, one on DVI-D), screen turns black while loading system in console
When only 1 monitor connected to VGA everything is fine.
There is no problem with kernel 5.2 or with amdpgu-dkms 19.10 on debian buster (linux 4.19)
It happens only with amdpgu-dkms 19.20 or 19.30 (on debian buster - kernel 4.19)
For 19.20 I applied my patch from https://bugs.freedesktop.org/show_bug.cgi?id=111103, which is merely the same as the code in 19.30
Bug still present in amdgpu-pro-19.30-855429-ubuntu-18.04
Last working version is amdgpu-pro-19.10-785425-ubuntu-18.04
Please attach your xorg log (if using X) and your dmesg output. What GPU are you using?
Thanks for your interest in that issue.
How could I do that with nothing visible on my monitors ? Is there any parameter I can add to the kernel to keep a log ?

System information (part2 = logs)
I could get the logs/info through SSH
There was no Xorg.log probably because the system didn't start X
There is no dedicated GPU on my system but an APU/CPU with integrated graphics :
"AMD Athlon 200GE with vega graphics"
BTW, running kernel 5.2.x was fine (both monitors had something displayed)
The issue seems to be related to these calls in file
If I delete them the display works also with 19.30
