Failed to load module on boot

NVIDIA Open GPU Kernel Modules Version

555.52.04

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

Fedora Linux 40 (KDE Plasma)

Kernel Release

Linux fedora 6.9.5-cb1.0.lto.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Jun 17 00:15:04 UTC 2024 x86_64 GNU/Linux

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 4070 Ti

Describe the bug

The open driver fails to load on the new linux kernel 6.9.5 consistently. This does not happen with either the 6.9.4 kernel or with the proprietary driver.

I have attached the filtered journalctl output: error.log

To Reproduce

Pre-requisites:

• Fedora 40
• linux-cachyos LTO kernel 6.9.5 + akmods

dnf copr enable bieszczaders/kernel-cachyos-lto
dnf install kernel-cachyos-lto kernel-cachyos-lto-devel-matched akmods

• Negativo17's fedora-nvidia repo

dnf config-manager --add-repo=https://negativo17.org/repos/fedora-nvidia.repo
dnf install nvidia-driver nvidia-driver-libs

---

1. Set kernel module type to open sed -i -e 's/kernel$/kernel-open/g' /etc/nvidia/kernel.conf
2. akmods --rebuild
3. reboot

More Info

No response

Start with the attached error.log and the repository's Linux kernel-module loading paths. Reproduce the boot failure on Fedora 40 with the 6.9.5 linux-cachyos LTO kernel and open modules, comparing it with 6.9.4 and the proprietary driver. Done means identifying and fixing the open-driver loading failure without regressing the working kernel cases.
