What you're doing is just stupendously wrong. As a privileged program, you
don't NEED to use key 8 storage and it is an integrity exposure to use key
8 CSA. The gymnastics you would have to go through to get what you're doing
to appear to work would further increase your exposures. Add to that the
fact that an ordinary prob state/key 8 task in another address space cannot
do a cross-memory post anyway (sounds like the likely reason for your
predicament) and you're just digging yourself a hole.

Don't do it. Don't even start doing it.

It is a whole lot easier to do it right from the start.
