--- Comment #2 from xtf1 at ymail.com ---
Distro:                 Arch

linux:                  1.16.11-1
xorg-server:            1.20.0-2
xf86-video-amdgpu:      18.0.1-2

Importance is low, because I'm mainly using it via vfio-pci in vm.
Worked in 4.15, so I was able to attach it to host when VM was off, never back
to guest, but that's a problem for another report. Here if boot directly with
amdgpu not blacklisted I get the panic

GPU actually never worked with xf86-video-radeon driver, only after switching
to amdgpu with 
options radeon cik_support=0 
options amdgpu cik_support=1 a
options amdgpu dpm=1 
in modprobe.d 


Done so far:
-blacklisted vfio-pci
-toggled options:
        -amdgpu.dc=1    (now: commmented out)
        -amdgpu.runpm=1 (now: commmented out)
