Re: PCI I/O region assigned to your NVIDIA device is invalid on linux>6.18

Also what do you mean "worked by accident"? Do you think I never had enough space and it was being assigned anyway??

That would be the alternative to a bug, yes.

that first commit's archive

You're not using git but fetch zips from github?
Are you replacing/rebuilding the entire kernel or only drivers/pci?
The offending commit being in that path is plausible, but by no means guaranteed.

https://github.com/archlinux/linux/comm … .13-arch1/ has 4 commits on top of the 6.18.13 base, largely dealing w/ (irrelevant on your system) amdgpu.
You're always using https://gitlab.archlinux.org/archlinux/ … fig.x86_64 ?

Re: PCI I/O region assigned to your NVIDIA device is invalid on linux>6.18

Yes, e.g. for the last build i set the source url to https://github.com/gregkh/linux/archive … 32d.tar.gz
I was rebuilding the kernel (although not cleanly, rerunning makepkg with existing cache on a clean docker instance), then installing the linux-lts and linux-lts-headers pkg.tar.zsts via pacman and rebuilding with nvidia-open-dkms
I can try building the whole thing from scratch from that commit again, alternatively I can try building 6.18.12 and maybe between .12 and .13 it got magically fixed again (since that pci commit is in .12 as well).
I use the linux 6.18.13 PKGBUILD as a base but I renamed the package to -lts since I want the package not to be named linux and mess up my current working kernel. I can try building 6.18.13 with the patches removed and see if that breaks it...

Oh. Nevermind, I thought I was building from the commit archive but I never changed the srcname...

This commit actually does work https://github.com/gregkh/linux/commit/ … 560cbdb770, I'll check the other ones tomorrow

Ok, so the breaking commit does in fact seem to be this one https://github.com/archlinux/linux/comm … f0d684b83d, I can try reverting it and trying to build a newer kernel version with that, not sure what else to do

Re: PCI I/O region assigned to your NVIDIA device is invalid on linux>6.18

Test the theory by only reverting the patch.
If you can demonstrate that it breaks your setup, you can (preferably) reply to the lkml patch, https://lore.kernel.org/all/20251219174 … tel.com/#R or contact the author directly (who will most likely take this to the lkml) and bring up your case.
I really can't say whether this is even potentially a bug or actually prevents you from undefined (but also any) behavior.
