TL;DR:
Random suspend / brief sleep during heavy GPU workloads on RTX 4050 (open DKMS) with ACPI & GPU errors.
System Specs:
- CPU: AMD Ryzen 7 7840HS (iGPU disabled in BIOS)
- GPU: NVIDIA RTX 4050 (open DKMS driver)
- RAM: 32 GB
- Kernel: 6.17.1-zen1-1 (also tried vanilla arch 6.17.1)
- Desktop Environment: KDE Plasma on Wayland (also tested Cinnamon on X)
tested both vulkan and openGL rendering
Issue:
During heavy GPU workloads (gaming, rendering, or any GPU-intensive task), the system occasionally goes into suspend or experiences a brief “sleep” state unexpectedly. Happens randomly on both KDE and Cinnamon.
No software crash; system just pauses and then resumes, sometimes accompanied by GPU/ACPI errors. Disabling sleep previously caused black-screens and OpenGL offscreen issues. I did not physically manipulate lid in any way.

Notes:
Lid close triggers suspend, network interfaces go unmanaged.
NVIDIA suspend service executes but doesn’t block system.
ACPI errors suggest missing battery symbol (_SB.PCI0.LPCB.BAT1).
AMD GPU resumes but DRM cannot find CRTCs.
NVRM reports GPU Xid error while Spotify was running.
