Just installed the headers for the new 2.6.25-1-AMD64 kernel this morning after having the kernel installed for a few days (headers were only installable today due to the proper kbuild package being missing till then from the repos).

Went to install the Nvidia drivers from their site as usual, and after I hit no to bypass the GCC check it got to 100% then failed. checked they log and it failed to make it.

It worked fine when I went back to the 2.6.24-AMD64 kernel.

Am I potentially missing something needed for the newer kernel to compile? Could it be that im using a newer version of GCC then the kernel was made with? (have always ignored it in the past but never had troubles) and if thats the case, anyone know the command offhand to force the Nvidia installer to use the older version of GCC? I forgot it and cant find that anywhere.

Maybe something is just not right with the new kbuild package? If thats the case I got no problems waiting it out, Sid is a unstable version that lets you get the newest packages. But if its something I am doing wrong or can fix I really would like to know.

Thanks guys

Known bug ... patches available from Nvidia ... or use "nv" drivers and wait.

i had same problem but for P4 32 bit.....i patched the nvidia legacy driver but it still failed to install

Running self compiled 2.6.25.1 with NVIDIA-Linux-x86-173.08-pkg1.run driver here, so try that.

in my case that driver will not work i use a legacy card

Better do what rickh said then, wait with kernel upgrade until it's fixed, or patch the kernel.

You can use the latest nvidia beta drivers (173.08 at the time of writting), their compatible and they build fine with the 2.6.25 kernel. Not all cards are supported though, check the compatibility list.
I've been using it for several days without a single problem on a 8600gts.

Weird thats the one I used that failed to install.
I think I read somewhere that it is only fixed for 32 bit kernels.

I'm pretty sure it works for 64bit too, but i've read your first post and you need full kernel source, not only the headers.

My kernel is home build but from sid sources, with gcc 4.2.

What does exactly the error message say ? Did you check /var/log/nvidia_installer.log after the failed attempt ?

I repacked the amd64 deb with the nvidia patches.

Just install it and it will work with module-assistant.

I have used it with built 2.6.25 and 2.6.25-1 kernels.

That's a nice move, thanks !

new version of kbuild for the 2.6.25-1 kernel is in the repositories today, it fixed the problem, drivers installed with the Nvidia installer flawlessly.

I just managed to get the .169 driver (for AMD64), with suggested patch, working on Lenny and a scratch/vanilla 2.6.25.1 kernel. Asus M2NPV-VM, chipset gF6150 & nF430. Got the original installer and the patch in the same dir, did the patch as suggested on the nvnews site and the custom installer worked first time Next step: MythTV (yeah, got the multimedia repo in my sources.list already )
