I am missing any indications that the dwarf data was *bad*, only
that it contains pre-relocation numbers as it always does. (And
it has to: relocation of the kernel is done at run time at an
unpredictable offset.) This is what the _stext-based relocation
logic for bug #4224 was for.
What seems to be wrong here is that the unrelocated addresses are
used by the runtime directly. It should have never done that, but
I wonder why it has appeared to work at all!
