NVIDIA driver not loading in Dell g3-3590 Ubuntu 21.04 nvidia-driver-470

Recently my nVIDIA card stopped working in ubuntu 21.04. I noticed constant CPU use and top showed modprobe using 44.5% CPU at all times.

Furhter investigation with udevadm monitor revealed the following scenario repeatedly:

UDEV  [601.231746] add      /bus/pci/drivers/nvidia-nvswitch (drivers)
UDEV  [601.234197] remove   /bus/pci/drivers/nvidia-nvswitch (drivers)
UDEV  [601.314627] add      /bus/pci/drivers/nvidia (drivers)
UDEV  [601.332429] remove   /bus/pci/drivers/nvidia (drivers)
KERNEL[601.590924] add      /bus/pci/drivers/nvidia-nvswitch (drivers)
KERNEL[601.591569] add      /bus/pci/drivers/nvidia (drivers)
KERNEL[601.591594] remove   /bus/pci/drivers/nvidia (drivers)
KERNEL[601.592254] remove   /bus/pci/drivers/nvidia-nvswitch (drivers)

dmesg revealed the following:

[  942.115453] nvidia-nvlink: Nvlink Core is being initialized, major device number 511
[  942.115458] NVRM: This is a 64-bit BAR mapped above 4GB by the system
               NVRM: BIOS or the Linux kernel, but the PCI bridge
               NVRM: immediately upstream of this GPU does not define
               NVRM: a matching prefetchable memory window.
[  942.116045] NVRM: This may be due to a known Linux kernel bug.  Please
               NVRM: see the README section on 64-bit BARs for additional
               NVRM: information.
[  942.116047] nvidia: probe of 0000:01:00.0 failed with error -1
[  942.116069] NVRM: The NVIDIA probe routine failed for 1 device(s).
[  942.116070] NVRM: None of the NVIDIA devices were initialized.
[  942.116556] nvidia-nvlink: Unregistered the Nvlink Core, major device number 511

Again, this repeats conmtinuously.

I really don`t have a clue how to fix it. GPU work flawlessly in Windows 10.

Looking at dmesg I found the following: `[ 1.238820] nvidia-gpu 0000:01:00.3: can't change power state from D3cold to D0 (config space inaccessible)` `[ 1.238828] nvidia-gpu 0000:01:00.3: can't change power state from D3cold to D0 (config space inaccessible)` `[ 1.239115] nvidia-gpu 0000:01:00.3: pci_alloc_irq_vectors err -22`

This problem is old. I just found the exact same problem in a ubuntu-bug mailing list post: https://ubuntu-bugs.narkive.com/eINzSDzw/bug-1742112-new-nvidia-graphics-card-failed-to-initialized

Have you found the solution yet?

I get the feeling this only affects the Dell G3 3590, as none of the solutions Ive found works. I have the exact same model and have the same problem. It also fails on Ubuntu 20.04. I have tried so many things spending over a week full time trying all sorts. I have found that Mint 19.3 works with 450 version of the drivers. I'm guessing Ubuntu 19 will too. It looks to me like a kernel bug, https://ubuntu-bugs.narkive.com/eINzSDzw/bug-1742112-new-nvidia-graphics-card-failed-to-initialized

Id really love to get this working properly.

The problem is that it worked quite well in ubuntu 20.04 until last june. Right now, I just purge the nvidia drivers and work with intel in ubuntu and switch to win10 for games.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
