This is universal kernel list and it is not read by many. I have added
hopefully right list (amd-gfx@...ts.freedesktop.org).

I have no influence or knowledge about this driver, but I still try to
help because it seems good bug report. Have you test with 5.13.13 or
5.14-rc7. Does this work with some other kernel? If needed can you git
bisect if needed? You will probably get some support for it if needed.
