Please file a bug report, and ideally bisect which commit(s) introduced the issue(s).

If that is true, again please bisect which commit broke it.
All the reports I've seen before this indicated that at least amdgpu has never worked with SME (which BTW doesn't mean it's never going to work or that we don't want to support it, just that as far as we know it's currently not working).
