I am having the same problem with a Toshiba Satellite 1710cds laptop, under Ubuntu 11.10 and 12.04 alt-iso for i386, it gets to the 14% mark with the language-pack-en-base, and the hard drive gets VERY busy, but the install does not proceed, even when left for 24 hours (I will let it run to see if it ever comes back)
this does NOT occur with the 10.04 alt-iso, that distro goes through the install without incident, its just that this laptop has no hope of running the gnome desktop ;)
