[Bug]: GSP task exception (Xid 120) causes dGPU to disappear from PCI bus after suspend on RTX 5060 laptop (driver 610.57.04)

Hardware: GPU

GPU 0: NVIDIA GeForce RTX 5060 Laptop GPU (UUID: GPU-0cbfb806-4fdb-15e6-3dad-ab503d487003)

Describe the bug

After suspending my laptop (systemctl suspend or just closing the lid), the NVIDIA dGPU doesn't come back when I resume. nvidia-smi can't find the device at all, and it's not just powered down, it's completely gone from the PCI bus until I do a full reboot.

I've tested this with /sys/bus/pci/devices/0000:01:00.0/power/control forced to both auto and on, and it happens either way. So it doesn't seem to be an RTD3/D3cold issue, it looks like a GSP firmware fault happening during the suspend transition itself.

To Reproduce

Boot normally and confirm the dGPU is present via nvidia-smi and lspci -D | grep -i nvidia.
Suspend the system (systemctl suspend, or just close the lid).
Resume.
The display may come back on the iGPU only, or hang. nvidia-smi reports no devices found, and lspci -D no longer lists the NVIDIA GPU at all.
A full reboot is needed to get the GPU back. A PCI rescan (echo 1 > /sys/bus/pci/devices/0000:01:00.0/rescan) doesn't bring it back.

Reproduce the failure with systemctl suspend and capture journalctl -k alongside nvidia-smi and lspci -D. Start in nvidia/nv.c around nv_suspend_devices, nv_set_system_power_state, nv_pm_notifier, and nv_restore_user_channels, using the reported Xid 120 and suspend warnings as the trace. Done means the RTX 5060 remains visible on the PCI bus after resume without the reported recovery failure.
