Systems are Intel Dual-Xeon with Fedora 41 and GCC 14.2.1..  Kernel compiled from kernel.org source..

Starting with driver 550.144.03, and now with the latest driver 570.86.16 I have been experiencing odd and inconsistent problems with the usual install process..

Running ./NVIDIA-Linux-x86_64-570.86.16.run fails with “ERROR: Unable to load the kernel module ‘nvidia-drm.ko’.” and later “-> Kernel module load error: No such file or directory
ERROR: The nvidia-drm kernel module failed to load. This kernel module is required for the proper operation of DRM-KMS.”
and later:
“ERROR: Installation has failed.”

This installation failure is inconsistent, and the driver will install correctly on one system, but fail on another similar system.  After updating the kernel (dot-release) the install may be OK, on a system where it had previously failed….
On a third test system (2023 HP Envy 17 Intel i7) the driver install sometimes – but not always – defaults to try to use the kernel-open stack, instead of the correct default of kernel, and needs the -m=kernel parameter adding to the NV…run command to work correctly.

The workaround is to compile and install the driver manually, and then everything completes successfully:

./NVIDIA-Linux-x86_64-570.86.16.run -x
cd NVIDIA-Linux-x86_64-570.86.16/kernel
make
(as root)
make modules_install
depmod -a
modprobe nvidia-drm (to load all the modules..)
./NVIDIA-Linux-x86_64-570.86.16.run -s –no-kernel-module – to install the userland components (libs etc)

It should be mentioned that the code compilation produces many compiler ‘warning’ messages:

Obviously, these are compiler warnings, and the code compiles successfully, but IMHO these should not be present in (hopefully) professionally-produced code, but seem to be accepted as the norm, now..
