Quick Install DVD Installs but hangs on boot

Hey Guys,
i've got a problem where I can deploy the image using the quick-install DVD all the way through, it ejects the disk and asks to continue, however on the first boot (and every one after) it will appear to have hung/locked about 1% of the progress bar for about 5 minutes, it will then dump to a shell with very limited commands.

From what I can see there are no logs etc, I have edited the runtime boot config to take away slient and splash so I can see what's happening - it appears to do everything correctly, the last thing it loads are the USB HID devices (keyboard and mouse) - i have even tried without these devices plugged in just in case it was one causing the problem

Any idea's anyone?
