Xorg.0.log with modesetting

+++ This bug was initially created as a clone of Bug #103953 +++

I have 3 Dell WQHD Screens (2560x1440) screens, connected to a Radeon RX580 (XFX, RX-580 GTS Black Edition, 1425 MHz 8GB).

My kernel is:

Linux edison 4.19.13-300.fc29.x86_64 #1 SMP Sat Dec 29 22:54:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

With the default boot settings, which enable amdgpu.dc, I am unable to get the native resolution on one of the three monitors.

If I disable amdgpu.dc on the kernel command line, I am able to get the native resolution on all three monitors.

I have attached the Xorg.0.conf.old from the startup with amdgpu.dc at the default setting, and Xorg.0.conf from the startup with amdgpu.dc=0.

I have also attached the initial part of the dmesg log from both boots:

dmesg-amdgpudcdefault.log : default amdgpu.dc setting (enabled)
dmesg-amdgpudc0.log : amdgpu.dc=0

The only relevant difference I see between the two is that with modesetting, I see the following errors:

 edison kernel: amdgpu: [powerplay] Failed to retrieve minimum clocks.
 edison kernel: amdgpu: [powerplay] Error in phm_get_clock_info 

whereas without modesetting I do not see those errors.

Still have this issue, with a totally different card: RX590 made by Asus.
