Hi Jyri,
I am often seeing only some moving horizontal white strips (maybe 1-2
pixels thick) when I boot my gta04 (omap 3 dm3730 + panel_tpo_td028ttec1
+ encoder_opa362).
After a git bisect session, the verdict is: this patch is guilthy:
commit 897145d0c7010b4e07fa9bc674b1dfb9a2c6fff9
Author: Jyri Sarha <jsarha@xxxxxx>
drm/omapdrm: Move commit_modeset_enables() before commit_planes()

Note: this seems also to depend on initialisation timings. I have
used a shell script as init to load the modules piece by piece.
