Unable to insmod - nvidia_uvm: disagrees about version of symbol nvUvmInterfaceDeviceCreate

[esp]

Hello,

I currently ran into an error when I tried to insert the module after compiling.

make modules

make modules_install

The modules seemed to be successfully installed.
But when I tried to insert the compiled module, an error in dmesg came out and I would like to know how to resolve this.

sudo rmmod nvidia_uvm

insmod /path/to/modules/nvidia-uvm.ko

I’ve already rebooted the machine but it didn’t help.

And I’m sure that I usually work with driver module with these steps and I can see the updated module works. But I don’t know why the module insertion is not well done in this time.

Typically that message comes when you compile your kernel module against a kernel tree that is not the same as your running kernel.

version.c - kernel/module/version.c - Linux source code v6.12-rc6 - Bootlin...

This is not an issue with nvidia-uvm itself. By any chance, did you upgrade your system packages but have not rebooted yet when you tried doing this. I suspect you have a newer kernel package than the kernel that is currently booted when you try to load the kernel module.

Might be good to compare uname -r and the path make modules_install installs the modules to for confirming you are building against the same kernel that is being run. Dumping lsmod | grep -i nvidia would also help.

The kernel version matches.

Could you tell me more about how to resolve this issue?

I just figured out the fact that the driver’s version and the driver installed doesn’t match.

nvidia-smi
With this, we can see the Driver version, and we should align the driver module we want to insert.

Thank you!
