Odd... That rework had its own issues and so several patches went in
subsequently to address them. It's possible that the PS3 does more
horrid stuff we missed here but I don't quite see how to relate that to
your specific memory corruption problem...

Do you see any "pattern" to the corruption ? Does it looks like
something known ? IE., exception frame, ASCII data, MSR values, ...

Ben.
