Can't load kernel module(nvidia.ko) on 8.0R
 

Hello,

I have a problem.

I have installed FreeBSD 8.0R.
And I have installed nvidia driver(190.36) from latest ports.

But the OS can not load nvidia kernel module(nvidia.ko).

Error message is

% kldload nvidia.ko
KLD nvidia.ko: depends on kernel - not available or version mismatch

What's happen?


I have tried other driver version( i.e. 190.42, 195.22).
But I have same error message.

Re: Can't load kernel module(nvidia.ko) on 8.0R
 

Version 190.36 is not from latest ports, it is 185.18.36. Do you mean direct install from nvidia site?

Try to set 'nvidia_load="YES"' in /boot/loader.conf and reboot. Then kldstat should show the loaded module nvidia.ko.

rhurlin, thank you for your reply.

I made a mistake. The version is 185.18.36.
I have installed the driver from latest ports.

But I tried other version(such as 190.42 and 195.22) too.

And I have already set 'nvidia_load="YES"' in /boot/loader.conf.

There is no 'nvidia.ko' in the message of kldstat.

I have seen this behaviour several times before. For me the following steps did work:

1. Completely deleting the nvidia-driver, e.g. pkg_delete nvidia-driver
2. Compiling of original xorg ports: portupgrade -f libGL libGLU libglut
3. Then installing the nvidia driver again
4. REBOOT

Afterwards the module should be loaded, see kldstat ...

Loading the driver with kldload does not work for me.
Hope this helps.

rhurlin, thank you for your reply again.

I have tried to do your suggestion.
But I sill have the trouble.

(I had already clean installed the OS(FreeBSD), ports(xorg etc.) and nvidia driver).

my kldstat messages are as follows,

mypc# ls
linker.hints nvidia.ko
mypc# kldstat
Id Refs Address Size Name
1 13 0xc0400000 b6dfe0 kernel
2 2 0xc0f6e000 2d8e4 linux.ko

mypc# kldload -v ./nvidia.ko

A few things to try:

Can you provide the following info:

pkg_info -Ix nvidia

ls -al /boot/modules

Have you recompiled your kernel at all recently? Are you indeed installing from the ports or not ? A while back, the NVIDIA drivers wouldn't install on 8 without the port as they did a version check that was disabled as part of the ports.

Nejdl, thank you for your reply.

I don't recompile the kernel of 8.0R.
I use original GENERIC kernel of 8.0R.

And I update ports tree every day( I perform portsnap command).
I use latest ports version.

In the case of installing other version of nvidia driver(such as 190.xx or 195.xx),
I have edited nv-freebsd.h by text editor(I removed version check part).


I have performed following work.

mypc# pkg_info -Ix nvidia
nvidia-driver-185.18.36 NVidia graphics card binary drivers for hardware OpenGL
ren

mypc# ls -la /boot/modules/

Re: Can't load kernel module(nvidia.ko) on 8.0R
 

Most likely your kernel sources are not in sync with the running kernel. Make sure you checked out (and compiled against) RELENG_8_0 sources.

Pdegoeje, thank you for your advice.

That's right!
The problem is solved for your advice.

I had updated the src-tree to RELENG_8.
I did not know relations of src-tree and the nvidia driver kernel module.

I'm grateful for your help.
