Kernel error with Kernel 5.14 when hibernating

[Erim]

Hey all,

I noticed that I regularly get kernel errors (see later). It seems they always get triggered before I hibernate my desktop pc.

While reading up on these errors (starting with “–[cut here]–”, it was suggested to report them to the upstream kernel, which I would like to. However, I’m unsure on where to report them.
Would the iommu mailing list mentioned here be the correct place?

@Erim

Would the iommu mailing list mentioned here be the correct place

Yes.

But before you do that, please read this first:

[HowTo] become a Manjaro power user when you're a wizard at Windows but a N00b at Manjaro / Linux

Difficulty: ☆☆☆☆☆ Remember when you installed your very first Windows, added bells and whistles and then couldn’t see the wood for the trees any more and had to re-install? Well, you’re in the same situation now: You’re a N00b again! Embrace it! I know right now you’re thinking:

Why is this so much more difficult than Windows?

Whereas in 6 months time, you’ll be like:

Why can't I make Windows jump through fiery hoops like I do with Linux???

<a class="lightbox&qu…

Especially the section Linux has multiple kernels and maybe the solution to your problem is simply an LTS kernel instead of filing bugs…

[Erim]

Trying other kernels was actually an idea I haven’t thought about, since I saw it for several of the previous kernels.
Now I finally got around to try various kernels and it turned out, that it doesn’t happen with kernel 5.4 LTS, but with 5.10 LTS and 5.13 and 5.14.

However, I’m still gonna contact the mailing lists, since it could be that some of the changes after 5.4 introduced that problem.

PS: Thank you for the Tutorial/HowTo. I knew a lot already, but it was still quite informative.

[Fabby]

I’ve marked this answer as the solution to your question as it is by far the best answer you’ll get.

Kernel error with Kernel 5.14 when hibernating

Yes. But before you do that, please read this first: Especially the section Linux has multiple kernels and maybe the solution to your problem is simply an LTS kernel instead of filing bugs…

However, if you disagree with my choice, please feel free to take any other answer as the solution to your question or even remove the solution altogether: You are in control! (If you disagree with my choice, just send me a personal message and explain why I shouldn’t have done this or or if you agree)

P.S. In the future, please don’t forget to come back to your question after your issue has been solved and click the 3 dots below the answer to mark a solution like this below the answer that helped you most:

so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.
