Hi Christian,
This is the information you asked for. Yes, I now know how to get around
the problem, but if you wish to explain more of what is going on, I would
be glad for the info. Thanks either way!

Toto, I have a feeling we're not in the mainframe world any more.

Do you use the SUSE provided s390tools or a selfcompiled version?
To catch most of the possible reasons:
Can you post the output of
- uname -a
- strace vmcp q userid
- stat /dev/vmcp
- cat /sys/class/misc/vmcp/dev
- rpm -qv s390-tools
- which vmcp
- file /usr/bin/vmcp
Thanks
Christian
