The interesting information I'm trying to get is exactly where os-prober froze, so if it finishes correctly then that information isn't going to help. I think at that point in the installer if you look, you will see the hard disk mounted under /target, and it has its own copy of os- prober, so make sure that it has the set -ex and let the installer install grub, and if it freezes there again ( and you should also check ps aux | grep os-prober to see if the process is still running ), then at that point all of the debug output should be in /var/log/syslog and we should be able to see where it was when it froze.
