Hi Paul,
I have removed my debug printk and not it boots and the drm interrupts come to an end.
BTW: Ethernet was broken with the printk inserted but is now working again.
So the logging code was standing on some brake.

Here is a hdmi-5.8-rc5.txt created on the latest kernel but by the same script.

If you do a diff to the working hdmi-3.0.8.txt you may check for significant
and insignificant differences. Most worrying to me is that the LCDC has some
quite different parameters. Using exactly the same panel it should be
almost the same...

BR,
Nikolaus
