Oh, sorry with d-i-n I meant drm-intel-nightly.
Normally, I also point to the "integration manifest"
like...drm-intel-nightly: 2016y-08m-02d-14h-10m-12s UTC integration
manifest.
You do not test d-i-n yourself?
Strange.
The Ubuntu kernel-team is regularly building packages see [1] if you
did not know.
