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.

Got 5.5.9 out; note that this kernel is compiled w/ gcc 9.3.0; you may need to pacman -Syu before building the new version (I'm not entirely sure since I did a roundabout way). Either way, the pre-compiled version is available on my repo.

And now my graphics card I've attached for use with VFIO isn't initializing correctly. Looking deeper it seems like this is a kernel issue, but I don't know the cause. Looking through dmesg, I get this: pci-stub 0000:07:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff and some message saying it couldn't turn on the device. Is anyone else having these problems? I'm building the LTS version of this kernel in the hopes it fixes my problems. I'll edit my post as I find more information.

EDIT: I should mention that it's not the card itself since I booted into Windows 10 briefly with it and it appears to work fine.

Seems my build wasn't working. If I use slowbro's build it works fine.

markzz commented on 2020-03-14 18:31

Did you try the regular arch kernel? This patchset does not touch anything regarding disk mounts.

osakasys commented on 2020-03-14 14:51

Getting an error when using fusermount: fuse: missing mountpoint parameter

Everything I can find points to this being a kernel issue.

EDIT: This may be fixed in 5.6 due to this commit
EDIT2: This problem seems to have been fixed by using slowbro's build. I think my gcc and gcc-libs versions may have been to blame.

Thanks slowbro for providing the updated version. much appreciated.

When I get back to Michigan this weekend, I'll be making a build for my repository as well.

Thanks, markzz. I just published a better version of 5.5.5 now, with updated kernel config - so if you already installed 5.5.5.arch1-1 from below, be sure to update to 5.5.5.arch1-2 from aur. Same kernel, just matches the 'linux' package's config.

I'll keep my eye out for upstream updates and try to get them released ASAP.

I have just added slowbro as a co-maintainer to assist me in keeping this up to date when I get into busy seasons like I have been trying to crawl out of. Sorry about the lack of updates and hopefully the two of us can keep this up to date more effectively than I can alone.
