[Solved] Failed to allocate NvKmsKapiDevice

SolarNyx · 2025-07-06 11:59:40

Unable to boot properly using the initramfs-linux.img but am able to using the initramfs-linux-fallback.img. Looking at journalctl for the failing boot there is the following error message. (Which i thought was the initramfs-linux.img boot but might actually be a initramfs-linux-fallback.img boot due to the very first log?)

Jul 06 12:03:21 archlinux kernel: [drm:nv_drm_register_drm_device [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to register device
Jul 06 12:03:21 archlinux kernel: [drm:nv_drm_load [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to allocate NvKmsKapiDevice

nvidia-smi output: https://pastebin.com/MwDQXWXq
journalctl -r -b -1 output: https://pastebin.com/c3dM4vRc

When on the initramfs-linux.img boot, gpu usage causes screen stuttering (Seen using nvtop), once the gpu usage stops so does the screen stuttering. (Hyprland as DE if relevant)

Added the following into /etc/mkinitcpio.conf

MODULES=(btrfs nvidia nvidia_modeset nvidia_uvm nvidia_drm)

Result of: pacman -Qs nvidia

Because it is like top posting.
Why not?
Please don't "-r".

Try to add "pcie_aspm=off" to the https://wiki.archlinux.org/title/Kernel_parameters and remove the nvidia modules from the initramfs.

Adding pcie_aspm=off resulted in it being unable to boot.

Just removing the nvidia modules, resulted in me being able to boot with both initramfs-linux.img and initramfs-linux-fallback.img

Still experiencing the 'gpu usage causes screen stuttering' but this is a separate issue I think then

What?
Unable to boot or unable to start a GUI?
Can you boot into the multi-user.target along "pcie_aspm=off" (2nd link below)?

maybe not, please post an updated system journal.
