The server is a SUN X2100 single Opteron server ( http://www.sun.com/servers/entry/x2100/index.jsp )

The only thing in which this server differs from the standard configuration is that lacking an internal cd-rom drive, I use an USB cd-rom drive to boot the installation cd.
However booting (Suse) Linux goes fine with this drive.
>How-To-Repeat:
1) insert installation cd (either 6.0R-AMD64 or 5.0-STABLE-SNAP10-amd64)
2) boot the system
