hw：i.mx6D； mipi display （5“ 720*1280）； LCD（0.65“ 800*600）

sw： linux3.17.53

question：

i have two display mipi display （5“ 720*1280）and LCD（0.65“ 800*600），When I give the LCD output，mipi display channel will be damaged，I use “ gst-launch -v videotestsrc ! imxv4l2sink device=/dev/video18 axis-top=0 axis-left=0 disp-width=800 disp-height=600 ” command。For example "clk_pllv3_av_set_rate: cannot configure divider when PLL is powered on" mistakes, but I don't know whether have correlation.The attachment is the shooting a video

please try commands given in attached Linux Guide sect.7.3.1.6 Video playback to multiple displays

and use L4.1.15 BSP :

The problem is not a simple multiple displays，LCD and hdmi is ok .this is kernel bug,I need to have a positive solution, rather than call me see manual.There is no reason why do explain, is to use a manual to my question.If it is so, why I need you help？？？
