[SOLVED] Boot warning/error message since update to linux 6.16

Hey,

so after installing the recent kernel I noticed a warning (or maybe an error) while booting the system.
The journal says:

...

amdgpu 0000:2d:00.0: amdgpu: psp reg (0x16063) wait timed out, mask: 80000000, read: 0 exp: 80000000
amdgpu 0000:2d:00.0: amdgpu: psp reg (0x16063) wait timed out, mask: 80000000, read: 0 exp: 80000000
amdgpu 0000:2d:00.0: amdgpu: psp reg (0x16063) wait timed out, mask: 80000000, read: 0 exp: 80000000
...

Other than that there is not much going on. Nothing broke. Suspend works. System is running fine.

I searched around and found this bug report, which links to a commit that introduces the warning/error.

My question now is, if this is something I need to further investigate. Or is this just a warning to be ignored?

edit: fixed the error message.

edit2: Fixed with patch to kernel. See thread for more infos.

This looks weird to me. The error message should also contain "read: %x exp: %x" at the end.
I cannot find a line of code in the current kernel sources, which matches your output.
At any rate, if the system behaves normally, you shouldn't worry too much about that.

Sorry, I fixed the error message. Got cut off by the terminal while copying and I didn't notice.

Then I'll let it slide for now and see if something comes up in the future. I'll just track the linked commits/files and bugs.

Should I mark this as solved or keep it open for now?

Re: [SOLVED] Boot warning/error message since update to linux 6.16

Exactly the same error message here:

amdgpu 0000:03:00.0: amdgpu: psp reg (0x16063) wait timed out, mask 80000000, read: 0 exp 80000000

I get it just 2 times.
This happened with the Kernel 6.16 update (I use Zen).
I have noticed no negative effects so far.
Not an actual issue but irritating.

Re: [SOLVED] Boot warning/error message since update to linux 6.16

After a full system upgrade I now get an error message:
amdgpu: psp reg (0x16063) wait timed out, mask: 80000000, read: 0 exp: 80000000 with 5 repeats.

Just a heads up for anyone who currently has the same problem. There is work being done to address this.

See this comment inside the bug report I shared in my original post.

Do you need help building a kernel with the patch applied?

Re: [SOLVED] Boot warning/error message since update to linux 6.16

Do you need help building a kernel with the patch applied?

That would be nice!

I did download the linux-zen PKGBUILD files and added the patch (named mypatch.patch) to source() and the folder .

Then I updated the checksums.

Also added inside prepare() like this:

patch -Np1 < "../mypatch.patch"

Then I do makepkg --skippgpcheck.

Sadly it tells me it fails patching the kernel with some error mentioning HUNKS. I don't have access to my Linux PC today, so I can't post the actual error message. I'll post it when I can.

The error basically tells me it can't patch one of the files of the mentioned patch. I suspect there are some more changes in there that it can't properly diff.

Is that the correct way of doing it? I have never done it myself, but that was everything I could gather for now.

That is all you need to do for the linux-zen package,  it already has code in prepare() to apply any source file ending in .patch.

Sadly the commit does not apply cleanly to 6.16.4 as you found:

$ patch -Np1 -i ../d56c7118fb48e87226b45810bc55eac3f5bc3a82.patch
patching file drivers/gpu/drm/amd/amdgpu/psp_v11_0.c
Hunk #1 FAILED at 149.
Hunk #2 FAILED at 397.
Hunk #3 succeeded at 666 (offset 1 line).
2 out of 3 hunks FAILED -- saving rejects to file drivers/gpu/drm/amd/amdgpu/psp_v11_0.c.rej

https://gitlab.freedesktop.org/agd5f/li … 55b8e959c3 needs to be applied first then the commit you want to test will apply cleanly.

Re: [SOLVED] Boot warning/error message since update to linux 6.16

Thanks, got it running. The patch solves the boot messages!

I did the following (just if other people are interested):

I cloned the linux-zen files. After that I downloaded both patches and named them 1.patch and 2.patch, so they get applied in the correct order. The patches get placed inside the cloned folder containing the PKGBUILD for linux-zen.

Then edit the PKGBUILD file and add '1.patch' and '2.patch' to the sources (right below config) and then run:

updpkgsums

That will update the PKGBUILD file with the correct checksums for the patches.

After that make the preparations for building the kernel. For that I ran the following command, which will only download and apply the patches. I did that so I can check if everything works as expected with the patches. Also I didn't want to deal with the keys, so I skipped checking them. I belive it doesn't matter for just trying out if the patched will fix the problem.

makepkg --skippgpcheck -o

After that compile the kernel with the following command, which simply builds the kernel. I noticed the compiling is pretty slow, so I followed this arch wiki chapter to enable all cores.

makepkg --skippgpcheck -e

After that just install with pacman -U.

Actually first time compiling the kernel, applying patches and messing around in a PKGBUILD file. Was a fun thing to do. Also reported to the bugtracker ticket. Thanks for the help!
