to mention here that I have experienced this kind of bug only when using the
"new" display code (amdgpu.dc=1).
I cannot strictly rule out that it could also happen with dc=0, since I have
tried dc=0 only for short periods occasionally, but during those periods I did
not see this kind of crash.</pre>
