System fails to resume from suspend with NVIDIA GSP heartbeat timeout

NVIDIA Open GPU Kernel Modules Version

595.58.03-2 (from package nvidia-open-dkms)

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

Arch Linux

Kernel Release

6.19.13-arch1-1 SMP PREEMPT_DYNAMIC Tue, 21 Apr 2026 23:38:22 +0000 x86_64 GNU/Linux (stable release)

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 3080 (UUID: GPU-8c983cec-3f59-dd0b-50c0-b0d42da360bb)

Describe the bug

After suspending the system, resume fails with NVIDIA GSP (Graphics System Processor) heartbeat timeout errors, followed by DRM atomic modeset failures. The system becomes unresponsive and requires a hard reset to recover.

To Reproduce

To Reproduce:

1. Use system normally
2. Suspend the system
3. Wait for any duration
4. Attempt to resume the system
5. Observe failure to resume properly, requiring hard reset

More Info

The problem appears to be that after the GSP heartbeat times out, the driver fails to properly reset the GPU and restore display configuration, leading to DRM atomic modeset failures.

Key error messages from journalctl:

Start by reviewing nvidia-bug-report.log.gz and the journalctl errors for the GSP heartbeat timeout and subsequent DRM atomic modeset failures. Trace the suspend/resume path for the NVIDIA open kernel driver and reproduce the failure on the listed Arch Linux kernel and RTX 3080 hardware. Done means resume completes reliably without heartbeat timeout, semaphore, or atomic modeset errors.
