I tracked down the difference. The system that was showing all zeros had been booted after writing the 2.4 kernel using silo. The kernel was never re-written using zipl later on. Once I did that, and used the eckd0 bootstrap program that the new s390-tools creates, things are the way I expect to see them.

No doubt it is different for s390x, but I had not seen it was changed with the 2.4.19 kernel - I'll have check later, but you could look in the source yourself (around head.S or something it includes if I recall) Rob
