I don't suppose you're installing to an SSD drive? My installs of the
regular version and the Alt version of 12.04 64bit were freezing while
installing to an SSD. 

I swapped it out for a hard drive and the problem went away. I'm thinking
this was just a hardware connection issue between my SSD drive and the
motherboard's sata port.
