nvidia.ko module does not load

[marcus_eskilsso]

Hi!

I was running the official amd-64 driver, but then after I had recompiled my linuxkernel one day it stopped loading =( told me it was some unknown symbol in module. You know how it goes =)

so I figured I'd run nvidia-installer again. all over.

but I get this:

Architecture-specific modutils configuration not found, using defaults
FATAL: Error inserting nvidia (/lib/modules/2.6.8/kernel/drivers/video/nvidia.ko): Unknown symbol in module, or unknown parameter (see dmesg)
make[2]: *** [package-install] Error 1
make[1]: *** [install] Error 2
make[1]: Leaving directory `/root/NVIDIA-Linux-x86_64-1.0-6111-pkg2/usr/src/nv'
make: *** [kernel_module_install] Error 2



and dmesg says

nvidia: module license 'NVIDIA' taints kernel.
nvidia: Unknown symbol register_ioctl32_conversion
nvidia: Unknown symbol unregister_ioctl32_conversion
nvidia: Unknown symbol sys_ioctl



I dunno.. is it some kernel option I unset that needs to be there? am I doomed to forever run the nv-xfree-driver and not nvidia?!

These are most likely not kernel config options, but rather the wrong kernel sources the driver is reading (or you have cleaned the kernel sources after installing). The kernel sources the driver should be getting should be configured for your kernel (the .config present and make prepare run at least). Check the installer log to be certain what kernel sources directory is being used, and make sure it is prepared with the kernel config.

[marcus_eskilsso]

it is using my /usr/src/kernel-sources-2.6.8 . That is also the sourcetree I use to compile my linux kernel.

and as I said, it used to work - now it doesn't.


also those symbols it looked for, they are not anywhere in my current System.map, I do believe they were around in the old one tho

[marcus_eskilsso]

yes.. here we go. I think somehow the nvidia installer was using my old System.map, so I copied the new one over the old one. Now I get new beautiful errors.

These symbols were defined in the old System.map, so if it read that it's not strange it got weird when it tried to call 'em. In the new one they are not around. I still feel this is some kernel option I have not set. Guessing they are related to 32bit-emulation.

[marcus_eskilsso]

There we go.

Turned on 32bit emulation in the core, and again it works like a charm.

Now I am starting to wonder if I shouldn't go back to the xfree-drivers. atleast they are 64 bit
