Re: screen goes blank when loading gma500_gfx (atom D2500)

fbcon is loaded so it isn't an issue.

I tried 3.10 kernel initially (the above messages are from it), next I tried 3.13 kernel too, and that one behaves exactly the same.

As far as I remember, this system never worked with graphics well. Previous kernel (from which I updated) was 3.2 which had no gma500 module (local build).

What are the steps to debug this further?

Check you have X86_SYSFB and SIMPLEFB disabled

Boot with drm.debug=6
