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 Reporter: frikraag@gmail.com
Created attachment 140310 --> https://bugs.freedesktop.org/attachment.cgi?id=140310&action=edit 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.
