I've attached 2 dmesgs.
This one is booting with my adapter and then switching to the HDMI port:
after.txt
And that one is booting straight with the HDMI port:
straight.txt
I don't know if it's my TV or my adapter, but one of them is peculiar because anytime I try such thing, I have trouble to get them working together again... But regular HDMI-HDMI works fine on regular kernels now unlike with your tree. The adapter worked fine with your tree.
Thank you!
