--- Comment #16 from Luis Botello <luis.botello.ortega at intel.com> ---
Issue is not seen anymore with that patch series. But display is showing no
image while running ./testdisplay -a and it goes into the following resolution:

CRTC(36):[7]  2560x1440 60 2560 2608 2640 2720 1440 1443 1448 1481 0x9 0x40
241500

Is there some way to force it or to set a higher timeout between each
resolution?
