A question here. You reproduce the problem by starting a domain and
booting it on the openSUSE-10.3-GM-x86_64-mini.iso CD-ROM? How do you
disassemble the area of memory that produces the problem? Are you using
"objdump" on the bootloader found on the iso file or are you using some
other trick?

Thanks for your help,
