Description

The Nouveau driver is missing in the kernel version 6.4.0-150600.21-default,
causing issues with GPU functionality. This problem does not occur in the
previous kernel version 5.14.21-150500.298.g40e256at, where the Nouveau driver
works as expected.

Steps to Reproduce

    Boot the system using the kernel version 6.4.0-150600.21-default.

    Attempt to list the Nouveau driver directory:
    bash

ls /lib/modules/$(uname -r)/kernel/drivers/gpu/drm/nouveau/

Observe that the directory is missing.

Attempt to include the Nouveau driver using dracut:
bash

    sudo dracut --force --add-drivers "nouveau"

    Observe that dracut reports the Nouveau driver cannot be found.

Expected Results

The Nouveau driver should be present and functional in kernel version
6.4.0-150600.21-default, similar to its presence and functionality in kernel
version 5.14.21-150500.298.g40e256at.
Actual Results

The Nouveau driver is missing from kernel version 6.4.0-150600.21-default,
leading to the following errors:

    ls: impossibile accedere a
'/lib/modules/6.4.0-150600.21-default/kernel/drivers/gpu/drm/nouveau/': File o
directory non esistente
    dracut-install: Failed to find module 'nouveau'

Workaround

Booting from the previous kernel version 5.14.21-150500.298.g40e256at resolves
the issue:

    Install and boot from kernel version 5.14.21-150500.298.g40e256at.
    Verify the Nouveau driver is present and functional.

Conclusion

Please investigate the absence of the Nouveau driver in kernel version
6.4.0-150600.21-default and provide a fix or update. This issue significantly
affects users relying on the Nouveau driver for their GPU functionality.
