Can you send me the output of "/usr/sbin/prtconf -pv" and a machine
description dump from this machine?

You can get the raw binary machine description blob under linux into a
file by simply doing a large enough read() on /dev/mdesc.  The read()
system call will return -EMSGSIZE until you pass in a large enough
sized buffer.

Thanks.
