We use i.mx6 core board and we found the lcd display will sometimes abnormal when we reboot the core board.  We checked the lvds clk signal and found the lvds clock signal no output when display abnormal.

We found a document from NXP website. EB821.  After checked the document, we think it is most like the problem we met.  But after we checked the software and found we already had this patch in the Linux kennel. and we still have this problem.. 

The problem happened when system just enter Linux. Normally lvds will output correct signal and display will normal too. When issue happed, lvds will no output and display will abnormal.

Can you help on this?  Thanks.
