Ok thanks. In this specific case (jump to bootstrap), I don't really care about the performance loss introduced by a sync, I'll keep one just after the mtmsr to make sure that the interrupt switch is fully done before I hack with srr0 and the MMU. For the relocatable code, I'll still unvestigate the issue for my own education, but I beleive I don't need it anymore, I just wrote most of the code in asm this morning ;-) (PPC asm is frightening at fist, but finally it was not so difficult). So thanks David and Michael (and thanks again to Terry Greeniaus), I now have all the elements I need to do what I want. -- E-Mail: BenH.
