I've read your reasoning. I don't believe it is completely correct. That
is why I haven't applied the patch. Reading through the chip manual in
more detail I think the problem is not that it just happens to keep writing
stuff until it closes the chip down but that the RISC instruction sequence
isnt stopped instantly but prattles on into memory for a frame. If so you've
merely fudged around most of the real problem
