Would you mind attaching the full dmesg? We'll have a look.

I sometimes get the attached dmesg splat when the GDM login screen times out and fades to black (presumably specifically when it finally sets DPMS off, which disables the vblank interrupt).

I've seen this for the first time today, so it might have been introduced by one of the DC changes which landed in amd-staging-drm-next since yesterday. But since it doesn't happen every time, I can't be sure of that yet.
