Kernel team, do you know what introduced this change?
No, we don't modify the vmap function at all. It seems unlikely that anything changing between -r6 and -r7 would cause this. It looks like the nvidia module is incorrectly detecting the number of arguments that vmap() takes. This is an x86_64-only codepath so difficult for me to diagnose.
I have gentoo-sources-2.6.12-r8 installed, along with nvidia-kernel-1.0.7667, but using gcc-3.4.3, and it works fine.
Rob: are you on amd64?
I made some new tests. I tried to recompile gentoo-sources-r6 (using gcc 3.4.4 then 4.0.1) and then nvidia-kernel 7667. Guess what ? It fails with the same vmap error, where it was succeeding before with an old r6. I thought it was a genkernel issue so I recompiled my kernel by hand : $ make mrpropper && make && make modules && make modules_install But I still have the issue.
OK that's it. There is no spoon. The issue was a ccache issue. I disabled it in my make.conf and now nvidia-kernel emerges correctly on r8. So I close the bug and set it to INVALID. Sorry for the noise.
