Questions:
Are you able to ssh into problematic device while replicate issue?
If the answer is not, what about press any key?

Comment 3 by robert.h...@quantatw.com, Jul 14 2016 

I can not ssh into DUT. When this issue happened, there is nothing to do. 
Press power button for 8 seconds, it can shut down.

Then your case is different w/ mine in comment #1

Comment 5 by robert.h...@quantatw.com, Jul 21 2016 

Update,

I verified again. Using comment #1 'restart ui' is workable. The screen will restore back. Attach our log file.
