I have the exact same problem with lockups during installation of Edgy i386 on a HP Pavilion AMD64 PC.
The computer has an Amethyst motherboard and Phoenix BIOS, so the problem is not restricted to ASUS motherboards. I previously had to install dapper with -nodma, to avoid lockups when mounting CD-ROMs. ** Attachment added: "output of dmidecode" http://librarian.launchpad.net/4197819/dmidecode.out -- freeze at startup https://launchpad.net/bugs/38263 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
