Full dmesg 2021-05-13

I recently managed to snag a Gigabyte "Eagle 12G" Radeon 6700 XT. I am running
latest Debian Testing with a 5.12.3 kernel (config based off Debian defaults)
and latest linux-firmware from git.

Upon installing the card into my system and booting, it outputs the warning
below into kern.log. The UI is 3D accellerated, there are no errors or warnings
in Xorg.log, but there is some graphical corruption and tearing in some games
or on KDE's panels that disappears when the object is repainted.

Neither this WARNING nor the corruption occurs when when I plug in my previous
video card, a Radeon Vega 64.

Please let me know if I can provide more information or test something.

full dmesg

I see the same in dmesg every boot, since the 5.12 kernel. AMD 6800 XT here.
Started around 5.12.4 somewhere I think.

--- Comment #2 from Jonathan Farrugia (jonfarr87@gmail.com) ---
Can confirm I also see this message with an RX 6800 (non XT).

It's still present as of Kernel 5.12.10

Tried earlier Kernels 5.12.8 and 5.12.6 - error was present there too.


If it's any help these are my specs:

Ryzen 5800X
Radeon 6800 (non XT)
Using Latest amdgpu firmware and Mesa 21.1.x


Let me know if there's anything else I can help with.

--- Comment #4 from heuborger@gmx.de ---
For me, this issue disappeared after updating the kernelto 5.13. 
I believe, this commit reverts the change that introduced this issue:
