Just to check, you've built 6f11f37459d8f, and then you cherry-picked
2f425cf5242a0 on top (not merged), and that already got you the warning
flood?

I'm probably blind, but I'm really not seeing where this pile of
properties is coming from. Can you pls also boot with drm.debug=0xe and
attach full dmesg? Plus your .config please.

Thanks, Daniel
