            Bug ID: 107021
           Summary: AMDGPU crash when Power Management switches off screen
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

Trace from dmesg

With "Screen Energy Saving" selected in KDE, my screen does not return to
active state when I use the keyboard or mouse. Instead, the screen remains
blank indefinitely, until system restart or Xorg is killed. This has occurred
in Gnome as well as KDE Plasma 5.13. Each time this occurs, dmesg shows a trace
similar to the one attached. The system only seems to lock when screen is
blanked by power management and I am able to eventually recover by SSHing in
and killing Xorg/SDDM. I have not experienced any issues with "Screen Energy
Saving" disabled.

Steps to reproduce:

1. Enable "Screen Energy Saving" in KDE (or it's Gnome equivalent).
2. Wait time specified and system will not return from screen sleep state.

Other relevant information:

Linux: Arch Linux
Kernel: 4.17.2
AMDGPU: 18.0.1
Xorg: 1.20.0
Hardware:
Motherboard: ROG CROSSHAIR VII HERO, BIOS 0702 05/29/2018
GPU: Radeon RX Vega 64

I have experienced the same symptom with plain X11 and xlock disabling the
screen. And this wasn't a new bug - have seen this behaviour at least a year
ago already. Given that I could work-around this by configuring X11 to not
disable the screen, I did not bother to create a seperate bug report on this
(especially given the much more grave system-crash-inducing instabilities that
plague this driver :-( )

Same issue on 4.18.0-rc3, also on a Vega 64. My machine also locks up whenever
I manually turn off my monitor with its physical button.
