The freezes can't me do anything.
So now I can report some extra infos
This release was downloaded form latest official torrent. ( but the problem was found on GNOME and Xfce edition that I tried , downloaded from latest official torrents.)
cat /etc/sabayon-{edition,release}

Before to "fix" chrooting in the system no freeze happened. But booting the system , freezes happened during "equo install --> unpacking" phase
I was able to start htop before a freeze came back and an "lspci -n" istance ate 100% 1 cpu thread. and equo unpacking phase freeze
Moving "/usr/sbin/lspci" fixed the problem but lspci could be use from various programs. It can't be implemented.
Runninng "eselect python set ..." at the moment seems to fix this issue.
Now I'm able to update the system or install a single package without any problem.
I will proceed to make a new installation with the same ISO on another disk as soon as possible and try to reproduce this.
Tnx
