Linux 6.14.7: new kernel message with amdgpu

A new message has appeared in kernel 6.14.7: (I get 4 of them after boot)

amdgpu 0000:03:00.0: amdgpu: [drm] amdgpu: AUX reply command not ACK: 0x02.

Any idea what it is about?

Edit: looks like it was noticed during the RC phase: https://lkml.org/lkml/2025/5/15/962
apparently they didn't think it was worth fixing in the release.

Re: Linux 6.14.7: new kernel message with amdgpu

the fix is putting the message to debug-level log output, so appart from a bit of spam in dmesg there is no problem due to that message. Details found here: https://gitlab.freedesktop.org/drm/amd/-/issues/4219

Ah I see you already found the LKML thread

apparently they didn't think it was worth fixing in the release

Only mainlined commits can go into the stable tree as per https://docs.kernel.org/process/stable- … rules.html, but it would of course have been an option to drop the backported patch. AFAIU it was a dependency for a bugfix patch though, therefore it stayed.

Is the fix not 2900720 drm/amd/display: Avoid flooding unnecessary info messages which is in 6.14.8?

@loqs, yes but with 6.14.7 you will get these messages atleast on startup So I guess it will be fixed with the upcoming stable package ^_^
