Hello All,

 

We are using custom board of imx6q(part number MCIMX6Q6AVT10AD) with two display 1. LCD(800x480) primary 2. HDMI(1920x1080@60) secondary. Both LCD working correct and we are using kernel 3.14.28.

 

We are facing issue that when HDMI output is working and if we restart LCD preview several times then we get following errors continuously on console. This result into that both LCD and HDMI stop working.
