imx-ipuv3 2400000.ipu: DC stop timeout after 50 ms

Hi All,

I would like to ask for your help, please.

We have a imx6 custom board with TX6Q-1110 processor.

The board drives an LVDS 10" screen with 90 degrees rotation.

The Linux version is 4.4.1

1-2 boots from 10 is generating error message(s):

"imx-ipuv3 2400000.ipu: DC stop timeout after 50 ms"

When the error comes up in half of these cases the screen remains blank and just the next reboot can get out from this state.

The error always happens right after or during the X-server start.

The appearance is very random not seems to be depending of any circumstances.
