No problem, managed to boot directly into a text terminal and grabbed DRM related dmesg log. Hopefully it's what you're looking for :)
Find it attached please.
Thanks, this was helpful. The failure is shown at
[ 3.263394] [drm:0xffffffffc0303583] bad framebuffer height 2304, should be >= 768 && <= 768
where the FB height is too large. But I'm puzzled why this happens. The only way seems to be tiling, which isn't supported by Linux' simple framebuffers AFAIK. All framebuffers are supposed to be linear.
You said that the resolution is 3840 x 2160, but the attached log says 1024x768. I guess that the former is the monitor's native resolution and the latter is the display mode?
The attached patch adds a few extra lines of debugging output. Could you please apply it, rebuild, and report back with the log.
Best regards Thomas
