Bug#991546: Acknowledgement (linux-image-5.10.0-8-amd64: soft lockup after screen does a sleep cycle (dpms off then on))
After bisecting, I get this SHA1 as the first to have fixed the issue
(at least, it's not showing as easily as before it). It makes sense as
the backtrace shows something in amdgpu and this is a bug fix :)

drm/amdgpu: fix the issue that retry constantly once the buffer is oversize
We cannot modify initial_domain every time while the retry starts. That
will cause the busy waiting that unable to switch to GTT while the vram
is not enough.

I also tried to simply cherry-pick it on top of v5.10 tag, and it seems
to also fix the issue.
Here's the bisect log, in case this single SHA1 is not enough:
