Ciao Fabrizio, I'm sorry, it is a kernel issue. I can start live or installed 3.2.0-4-486 but not 3.2.0-4-686-pae, while I usually run guest ArcheOS Caesar with 2.6.32-5-686 and my host machine with "Linux gnewstar 3.2.0-4-686-pae #1 SMP Debian 3.2.35-2 i686 GNU/Linux". Maybe the problem is in some hardware driver? Thanks
