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.

Like markzz was, I'm providing updated builds in my (unofficial) user repository, if you don't want to build this yourself.

Zauberfish: Can you kindly read the wiki before being the 40,000th person to ask this?

Zauberfisch commented on 2020-04-08 03:20

I see the pinned comment saying I need to add 2 keys. But for me I still get an additional key error:

FAILED (unknown public key A5E9288C4FA415FA) ==> ERROR: One or more PGP signatures could not be verified!

seems the key for "Jan Alexander Steffens (heftig)" is also missing.

@giostark seems I have to dig deeper. After booting the default arch kernel, the problem continues to exist.

giostark commented on 2020-04-04 16:36

@PrfStrwberry- I have a 7700K and differ for two instruction from your: Intel® vPro™ Platform Eligibility and Intel® Trusted Execution Technology. And to me the mitigations seems to work. In general mitigation come activate host side but is not mandatory that the guest will use them. Those security mitigations are for you really necessary? Are you using those for networking VMs. Seems not bios options are available in Asus firmware. Kernel side I'm a noob so I can't say a thing. Thanks slowbro and markzz for your work. Me too I could not make my stuffs without this kernel.

Hey thanks for keeping this package up to date. I could not do anything without it. I am using an i7 8700k with an ASUS Maximus X CODE. I just have a small problem, after compiling and installing everything. When I create a VM inside virt-manager, I cannot enable and apply the box at enable cpu flaw mitigations. After clicking and applying, the tickbox goes blank again. Any tips?

ShayBox, it's unfortunately just the one little server on the west coast; it was probably busy with the binge watching I was doing on Plex last night. Should be okay now?

markzz commented on 2020-03-28 15:30

I'm going to set up my build system again and keep this package up to date as regards to this PKGBUILD to keep it up to date on my repository. The 5.5.13.arch1-1 is built and up on my repository.

markzz commented on 2020-03-28 04:41

This is my queue to actually use my work from home time and compile a new version of the package.

ShayBox commented on 2020-03-28 01:54

slowbro your repo is running at a few hundred kbps

slowbro commented on 2020-03-27 18:23

Sorry for the update delay; I had made 5.5.10, but then forgot to push it. Then work-from-home happened and things have been cuh-ray-zee.

5.5.13 is up now. If anyone is using my repo, as an FYI, I have switched to zstd (.tar.zst).

I hope everyone is doing well.
