^^^^^^^^^^^^^^^^ GR02, aka
the return pointer

^^^^^^^^^^^^^^^^
cr19 is the "IIR", this is the insn that caused the fault
in this case, this insn is stw r1,4(sr0,r29)

^^^^^^^^^^^^^^^^ which looks quite bogus

this is the "iaoq" -- the instruction pointer

is this the system.map from the kernel you are building?
if it is, then intr_return is the calling function (one up in the
stack). the function that includes 1010863c is the one that one that's
causing the fault. that would be one place to look.
