A few things BEFORE building this package and/or commenting here:


If you do not read the wiki and ask a stupid question, you'll either get a stupid/terse response from me or you will be ignored. If this continues, this may require me to bring this up to a TU for account suspensions.

Remember, there's also search engines that you can also look up errors that you get related to makepkg.


This package's goal is to be as close to the Arch Linux linux package. Therefore, we use the config file from that package. We will not, unless under very special circumstances, modify the config file for any reason.

You can make changes yourself. You should be capable enough to make any changes you see fit without us making the changes on our end.


This one has been more recent. The goal of this package is to add a MINIMAL patch set for IOMMU grouping and for VGA arbitration on Intel iGPUs. Under no circumstances will I backport patches that are not present in the linux repository on nor will I add a patch that adds a feature outside of the intended goal of this project.

If you absolutely feel that your patch is completely necessary, you MUST have ready a link to the appropriate discussion from the OFFICIAL LINUX KERNEL MAILING LISTS and/or from Arch Linux's Bug Tracker at For the latter, they must be bugs present in the linux package in [core] and do NOT open a task on there if it is specific to this package (or any AUR package for that matter). I do not want to see links to reddit talking about some patch that you want to add.

If you want to add patches to your own build, that's completely fine.


AUR helpers are unsupported and therefore we will not provide help to you unless you have verified it's not working with makepkg. I always make sure this package builds in a clean chroot before uploading here, so I know it builds on a clean and up to date Arch Linux system.


Both maintainers of this package provide signed binary packages in unofficial pacman repositories maintained and signed by ourselves. If you do not want to compile this kernel yourself for whatever reason, feel free to make use of them.

@pagdot Thanks for catching that, fixed.

@markzz Feel free to comment if you have any technical input, but I'd suggest keeping the passive aggressive comments to yourself next time. It's just software, it's not that deep. That's all I'll be discussing on that topic.

Yeah, turns out, maintaining this package is not always just updating the version number and grabbing a new config. I'll work on an updated patch today.

I strongly suggest rebuilding this after updating openssl to 3.0.7 (or better, building in a clean chroot which has an updated openssl), as this may break things otherwise.

Firebug24k commented on 2022-10-31 04:25 (UTC)

Same problem here - I can't get 6.0.5 to boot, it hangs as soon as it gets to the framebuffer.

TieMajor commented on 2022-10-17 06:22 (UTC)

6.0.2.arch1-1 is causing weird issues for me. The initial framebuffer seems to be broken (I am not using quiet), but when the xorg or wayland session starts it works fine. Trying to troubleshoot this I only found out it happens when I specify ids with vfio-pci.ids as a kernel parameter.

The symtoms are extremly similar to this post

The package has been out of date for a while now. Is the package definitely stopped? Can we expect an update soon? Is there any other solution than to do all the hand :( In any case, thank you for your time and skills.

Has anyone tried the Manjaro kernel with the ACS patch on Arch Linux? (linux-acs-manjaro)

giostark commented on 2022-06-05 00:58 (UTC)

Maybe a tip for other noobs like me. Now the system update work with the gcc 12.1. Installing the pre-compiled kernel (done with gcc 11.2) or via helper (yay always search for gcc 11.2) result in error with the latest nvidia modules (that use the gcc 12.1). Solutions: 1) downgrade the gcc to the 11.2 (bleah solution) 2) (better solution) compile the kernel from the source without helpers using: makepkg -Crso Then: makepkg -ers Then: sudo pacman -U (3 packs generated before) Here the topic of the issue:

pssst, this version is 2 patches old now
