System freeze after suspend/resume on Wayland + GNOME with open driver 595.71.05

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 Linux (rolling)

Kernel Release

7.0.5-1-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

NVIDIA GeForce RTX 4060 Laptop GPU

Describe the bug

The system completely freezes after resuming from suspend (sleep) while
running a GNOME Wayland session. The screen is frozen, no input works,
and the only way out is a forced reboot.

Before the freeze, the following critical errors appear in the journal:

• gnome-shell: "Cursor update failed: drmModeAtomicCommit: Invalid argument"
• Xwayland crashes with a backtrace ending in:
  drmIoctl / drmSyncobjTimelineWait / libnvidia-glcore.so.595.71.05

At boot, the driver also reports:
NVRM: GPU0 nvAssertOkFailedNoLog: Assertion failed: Invalid data passed
[NV_ERR_INVALID_DATA] ...

To Reproduce

• Use GNOME on Wayland with an external HDMI monitor connected
  to the NVIDIA GPU
• Put the system to sleep (suspend/s2idle)
• Wake the system
• After some time (sometimes immediately, sometimes after minutes),
  the desktop freezes completely

More Info

Additional logs from journalctl (previous boot with the freeze):
journalctl -b -1 | grep -iE "nvrm|gpu|xwayland|mutter|drm|hang|lockup"

Key lines:
gnome-shell: Cursor update failed: drmModeAtomicCommit: Invalid argument
Xwayland crash: drmIoctl -> drmSyncobjTimelineWait -> libnvidia-glcore.so.595.71.05

Start with the attached nvidia-bug-report.log.gz and the journalctl output from the previous boot, focusing on the GNOME Shell DRM error, Xwayland backtrace, and NVRM assertion. Reproduce the suspend/resume sequence with GNOME Wayland and an external HDMI monitor, then verify that the system resumes without the freeze or corresponding errors.
