I've just found yet another SC problem.  Due bugs in a certain ARC firmware
in the FlushAllCaches() function Milo uses it's own cache flushing routine.
Which does not has the feature of flushing R4000 caches 32 times in a row,
it also doesn't correctly deal with R4000 second level caches.  It just
happens to work for the Magnum 4000SCs because they use a unified second
level cache.

Any success in finally getting rid of Milo?
