ASUS ZenBook Q408UG keyboard not working

Hi list, 

My Asus ZenBook Q408UG's keyboard doesn't work on the coldboot, and
wanted your suggestions on how to get around it. 

During the probe, i8042_wait_read() times out. The avg reps for my
system is 13000 so below should do, but I wonder there could be a
better approach to resolve this issue.
