Folks, I think we have a real winner here. To my green-horned point
of view (WRT linker/compiler issues), it looks as though the .comment
section points to exactly the same place as the .bss does. I'm
guessing that the READONLY attributes takes precedence on that chunk
of code for at least the first 0x4f10 bytes of code.
Am I mistaken, or is this an overwrite (i.e. shouldn't file off for
.comment really be 0x14f400 + 0x23d54, or 0x173154)?
interesting theory. i'll only note that the above quoted text is from
the "working kernel" set, and that they both (ie, working and non) do
exactly the same thing here.
