Can you remove the 'rhgb' and 'quiet' from the kernel command line in the grub entry and tell us if there is anything else printed?

Is the machine accessible via the network?  Can you ping it or ssh into it?

Does the light on the capslock key toggle off/on when you hit it?

Thanks, I tried your instructions on kernel 3.3.0-0.rc4.git1.2.fc18.x86_64 and I see interesting stuff happening:
up to 5 seconds it is dealing with drm
some pause
at 9 seconds a message about udev stack depth
a bit bigger pause
at 25 seconds dracut kicks in and all the rest of commands issued will start slowly go up. each step is about 20 seconds apart. I regained a system login prompt in about 520 seconds!

So, it seems the kernel is still starting up, but all is a very slow process.

Note: The system is running off a SSD drive.

Comment 5 Josh Boyer 2012-02-23 20:51:44 UTC 
There was a bad patch included in 3.3.0-0.rc4.git1.2.  Can you try 3.3.0-0.rc4.git3.1 (or any kernel after and including 3.3.0-0.rc4.git1.4)?

The slowness might be a duplicate of bug 795050
Comment 6 Ivo Sarak 2012-02-23 23:43:29 UTC 
Thanks. It seems that it is the same case as update to kernel 3.3.0-0.rc4.git3.1.fc18.x86_64 resolved that issue for now.
