Hi,

Thanks for looking into this, but I have some questions.

Upstream commit d3f66064cf43bd7338a79174bd0ff60c4ecbdf6d titled:
Partially revert "amdgpu: DMCUB updates for DCN 3.1.4 and 3.1.5"

That does indeed seem relevant to the error msgs you posted in this bug.
That commit links to https://gitlab.freedesktop.org/drm/amd/-/issues/2666 
which is rather different from the 'Forwarded' URL/issue.
Was the initial Forwarded incorrect or am I missing something?

"This partially reverts commit ade163aaaeae0c1ad20cb3dd8ce878bf61c91b3a" is 
also part of that commit msg, but that commit was NOT part of version 
20230515, but 20230625 which has not (yet?) been uploaded to Debian.

Which leads me to conclude that you shouldn't have been affected as Debian's 
firmware package (version) does not include the commit which caused the issue.
Can you shed some light on this discrepancy?

Similar as above as it shouldn't have the commit _causing_ the issue.
