my platform is imx6dl,on which run Android6.0.1 OS (kernel 4.1.15) , the lcd display is normal ,but when the board is run for a long time about several days, the LCD display is abnormal ,and I print the log by uart console,it always print:

mxc_sdc_fb fb@0: timeout when waiting for flip irq

 

How to solve it ? Thanks
