we have a bunch of Zotac ZBOX NANO-AQ01 with this APU:

[ 2.234372] [drm] initializing kernel modesetting (KABINI 0x1002:0x9832 0x1002:0x0123).

For our application, we force 1440x900 resolution via this modeline ("cvt 1440 900"):

Modeline    "1440x900"  106.50  1440 1528 1672 1904  900 903 909 934

-hsync +vsync

The application is Chromium in kiosk mode. The problem is that sometimes the screen stays black after KMS kicks in.

So the problem occurs even without X? Does it affect HDMI or DisplayPort, or both?
