kernel panic

This is a follow-up from bug
https://bugs.freedesktop.org/show_bug.=
cgi?id=3D105018. If I leave my laptop in
its dock (one HDMI and one DisplayPort) it has a high chance of kernel
panicking when DPMS turns the displays off. This affects my Dell Precision =
7720
with a Radeon Pro WX 7100 on Archlinux, kernel 4.18.5. My boot parameters
include amdgpu.dc=3D1 (a redundant option nowadays, I know, I forgot to rem=
ove
this option). Suspend/resume work are fine, this happens only immediately a=
fter
idle blanking. As far as I can tell this does not occur when using only the
laptop screen but I could be wrong as I spend the majority of my time on the
dock.


I've attached a kernel log. For now I work around the issue by disabling dp=
ms
entirely.

Thank you!
