I started to look around for this error messages and found the following mailing list.
https://www.spinics.net/lists/kernel/msg4097048.html
First it proposed a patch to silence those error messages as they aren't lethal but after some research another patch was proposed which actually solved the issue I think.
https://lists.linuxfoundation.org/pipermail/iommu/2021-October/059955.html
It is quite small and it seems that it didn't get the required attention. I added the patch to the linux PKGBUILD and the errors no longer appear. Is there a possibility to add that patch to the linux package? Don't really want to build the kernel every time it is updated.
Hopefully I can get their attention in this list. Should I try to email them directly? On 11/14/21 12:04, KSP Atlas via arch-general wrote:

I started to look around for this error messages and found the following mailing list.
https://www.spinics.net/lists/kernel/msg4097048.html
First it proposed a patch to silence those error messages as they aren't lethal but after some research another patch was proposed which actually solved the issue I think.
https://lists.linuxfoundation.org/pipermail/iommu/2021-October/059955.html
It is quite small and it seems that it didn't get the required attention. I added the patch to the linux PKGBUILD and the errors no longer appear. Is there a possibility to add that patch to the linux package? Don't really want to build the kernel every time it is updated.
Yes. On Sun, Nov 14, 2021 at 12:14:55PM -0500, jk via arch-general wrote:
Hopefully I can get their attention in this list. Should I try to email them directly?

If you want to get the patch into the kernel, ask the mantainers: Tobias Powalowski, Jan Alexander Steffens and David Runge.
