gpu-unlock module loading order and conflict resolution with NVIDIA's proprietary driver within Ubuntu's `initramfs-tools`.

Technical Positioning
gpu-unlock aims for seamless integration and successful unlocking on various Linux distributions, requiring precise control over kernel module loading.
SaaS Insight & Market Implications
This issue identifies a critical race condition in Ubuntu's `initramfs-tools` that prevents `gpu-unlock` from functioning. The NVIDIA driver (`nvidia.ko`) is loaded and binds the GPU prematurely via `udev`'s coldplug trigger, before `gpu-unlock` has a chance to execute, resulting in an `-EBUSY` error. This highlights a significant developer pain point: the non-deterministic and distribution-specific nature of kernel module loading during early boot. `gpu-unlock` requires exclusive access to the GPU for its low-level operations, which is thwarted by the default `initramfs` behavior. Market implications are direct: `gpu-unlock`'s reliability on Ubuntu, a widely used distribution, is compromised without a robust mechanism to enforce correct module loading order, limiting its practical deployment and increasing user frustration.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Oct 23, 2026
Repo: Zagitta/gpu-unlock
Ubuntu/initramfs-tools: nvidia.ko in the initramfs binds the card before gpu_unlock loads (unlock fails with -EBUSY)

## Environment
- Ubuntu 22.04.2 LTS, kernel 6.8.0-138-generic (HWE)
- NVIDIA driver 595.99.02 from Ubuntu packages (nvidia-dkms-595), GA102 RTX 3090 (10de:2204)
- gpu-unlock 1.0.0, built from source via `make deb` (gpu-unlock-dkms + gpu-unlock-firmware installed)
- SecureBoot disabled, cold power-off boot, kernel cmdline `gpu_unlock.targets=all`

## Symptom
After installing and cold-booting, the unlock fails and nvidia binds normally (no unlock):

$ journalctl -k -b | grep gpu_unlock
... kernel: Command line: ... ro gpu_unlock.targets=all
... kernel: NVRM: loading NVIDIA UNIX x86_64 Kernel Module 595.99.02 ...
... kernel: nvidia 0000:01:00.0: gpu_unlock: unlock failed (-16)

(-16 = -EBUSY, from the `pdev->driver` check in `unlock_one()`.)

## Root cause
Ubuntu's nvidia driver packages place `nvidia.ko` (and GSP firmware) inside the initramfs (`usr/lib/modules//updates/dkms/nvidia.ko`). In initramfs-tools' `/init`, the execution order is:

run_scripts /scripts/init-top # starts udevd and runs the coldplug trigger
...
load_modules # only here does /conf/modules get modprobed

`run_scripts /scripts/init-top` runs `scripts/init-top/udev`, whose coldplug trigger autoplugs the PCI device and loads nvidia immediately. `/conf/modules` (where `/usr/share/initramfs-tools/modules.d/gpu-unlock.conf` ends up) is only processed afterwards by `load_modules`, so gpu_unlock's init runs with the card already bound and correctly refuses ...

I've seen some other reports that supposedly it works for AD102 as well but I don't have a card to test on myself. I'm happy to expand the allowed device IDs to AD102 as well if I see concrete evid...

This would be definetly also interesting for 4070 Ti Super, as it also uses the AD103. I have this GPU here, so I could test this if somebody gives me a small guide on what to modify and what tests...

Re-posting here rather than as a separate issue, since AD10x support was already discussed in this thread. Three AD106 cards (RTX 4060 Ti, `10de:2803`), cold boot, no driver bound, `driver=`, `stat...
