This is what I see on my screen before the computer freezes: Loading Linux 3.5.0-##-generic... Loading initial ramdisk... 3.5 boots with nomodeset, but the maximum possible screen resolution is too low (1024×768) and there is some sort of colour artifacts, making the desktop unusable in that case. I've tested on the latest upstream kernel too (v3.8-rc4), but the bug is still present.
