The psw and looping would indicate that zeros have
been loaded into the first 4K or memory. When the boot
loader branches to memory, an a zero psw is loaded, an
interrupt occurs, a zero interrupt handler psw is
loaded which then causes the recursive looping
(reloading of the same zero psw).

How are you building your system? from tape or cd? If
tape, what tape drives?

I think that I'm one of the few that actually use
LPARs, but I tend to build my LPAR systems under VM
because that is better tested and most often used. I
found tape build was combersome.

I assume that you have a SuSE License - I would report
the problem to SuSE ASAP.
