Yep, I get a "need a disk object" or some such similar error message. This is 
with Adobe Reader 7.

Hi Brad.  Thanks for the response.  When I try to open your link/pdf, I get

Check out this presentation on linuxvm.org:

Help! My (Virtual) Penguin Is Sick!

There's a section on VMDUMP, which will give you a kernel memory dump.
You'll need to convert it using 'vmconvert', which is available in the 
s390utils package.  This is assuming you're using DASD.  If it's a zFCP-only 
setup, the process is a little different.
