GPU Usage spiking at 100% after waking from suspend

NVIDIA Open GPU Kernel Modules Version

595.71.05

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Operating System and Version

CachyOS

Kernel Release

Linux cachyos-x8664 7.0.5-2-cachyos

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

• I am running on a stable kernel release.

Hardware: GPU

GeForce RTX 5060

Describe the bug

Issue: GPU stuck at 100% utilization after resume from suspend, persists until reboot. Memory utilization remains at 1%, clocks are normal, no single process attributed. Occurs immediately on wake with dual monitor setup (4K@120Hz + 1080p@200Hz).
Workaround: Full reboot required to restore normal GPU behavior

To Reproduce

This happens on any wake from suspend so I am unsure of what the other requirements are.

More Info

I feel like the bug report should have included more information, but that was the entire output.

Start with the reported nvidia-bug-report.log.gz and reproduce a suspend/resume cycle using the listed CachyOS kernel, RTX 5060, and dual-monitor configuration. Compare GPU utilization immediately after wake and determine what evidence identifies the responsible component; done means utilization returns to normal after resume without requiring a reboot.
