Interesting.  This might be fixed.  Could you please try

Otherwise, I'd like to work with you to gather more data from the "Page
Fault" event, in particular attach a serial cable, and type ftrace at
the ok prompt after the fault.

We can also use the debugger to step through to the point of failure.

(If the problem is reproducible with a deployment build, then I can try
downloading it, but my download budget needs attention and care.  I
generally only download the OLPC builds.)
