This could be a symptom and not the problem. What the above shows is
that ftrace tried to convert the mcount at change_protection but what
it expected was there wasn't. Unfortunately, it doesn't state exactly
what it wants (that would take a arch specific function to do that, and
this is in generic code). But what it found was "74 66 74 70", which I
have no idea what type of command that is.

This is big endian, so I think that's:

  andis.  r6,r3,29808

Which is feasible.

It also says "tftp", which is intriguing if nothing else :-)
