Comment(by andy):

 My guess is this problem belongs to the specific unit FWIW, likely
 something to do with total current on that device or something physical
 about a PMU inductor that makes it resonate.

 When we change to landscape orientation the speed of the Glamo video unit
 changes and so does the total amount of current drawn, I guess the PMU is
 feeling that for some reason.
