Title:
Ubuntu 26.04 kernel 7.0.0-14: suspend crashes with NVIDIA GTX 1650 Mobile / Max-Q in nvidia_modeset nvkms_kthread_q_callback / jump_label BUG

System:
- Laptop: Dell Inspiron 7501
- OS: Ubuntu 26.04 LTS “resolute”
- Kernel: 7.0.0-14-generic
- Desktop: GNOME on Wayland
- GPU: NVIDIA GeForce GTX 1650 Mobile / Max-Q, TU117M
- Hybrid graphics: Intel iGPU + NVIDIA dGPU
- External display connected via HDMI; external display requires NVIDIA mode
- Current PRIME mode: nvidia
- Current NVIDIA driver: nvidia-driver-595 proprietary, 595.58.03
- Also reproduced with:
  - nvidia-driver-580 proprietary, 580.142
  - nvidia-driver-595-open, 595.58.03
  - nvidia-driver-595 proprietary, 595.58.03
- NVIDIA suspend/resume/hibernate services are enabled.
- PreserveVideoMemoryAllocations is enabled:
  PreserveVideoMemoryAllocations: 1

Problem:
When I select Suspend, the system shows a kernel trace/panic and then becomes unusable. Sometimes it briefly reaches the lock screen/black screen, but keyboard/mouse cannot wake it. I have to force power off.

The problem happens with both suspend modes:
- s2idle
- deep

The problem happens with both NVIDIA 595 open and proprietary modules,
and also with NVIDIA 580 proprietary.

Expected result:
System suspends and resumes normally.

Actual result:
Kernel BUG/Oops during suspend in nvidia_modeset.

Relevant log excerpt:
PM: suspend entry (s2idle)
jump_label: Fatal kernel bug, unexpected op at nvkms_kthread_q_callback+0x8e/0x1a0 [nvidia_modeset] (...) size:5 type:1
kernel BUG at arch/x86/kernel/jump_label.c:73!
Oops: invalid opcode: 0000 [#1] SMP NOPTI
Call Trace:
 pm_suspend+0x49/0x90

Same issue with deep:
PM: suspend entry (deep)
jump_label: Fatal kernel bug, unexpected op at nvkms_kthread_q_callback+0x8e/0x1a0 [nvidia_modeset] (...) size:5 type:1
kernel BUG at arch/x86/kernel/jump_label.c:73!
Oops: invalid opcode: 0000 [#1] SMP NOPTI
Call Trace:
 pm_suspend+0x49/0x90

Troubleshooting already performed:
- Confirmed NVIDIA DKMS builds successfully for kernel 7.0.0-14.
- Confirmed nvidia-smi works normally before suspend.
- Confirmed nvidia-suspend.service, nvidia-resume.service, and nvidia-hibernate.service are enabled.
- Confirmed PreserveVideoMemoryAllocations=1.
- Tested s2idle and deep sleep.
- Tested nvidia-driver-580 proprietary.
- Tested nvidia-driver-595-open.
- Tested nvidia-driver-595 proprietary.
- Tested PRIME Intel-only mode; external monitor does not work in Intel mode, so NVIDIA mode is required for my normal setup.

Impact:
Suspend is unusable on Ubuntu 26.04 with NVIDIA mode enabled. The system must be force powered off after attempting suspend.
