Stuck at Apple logo post install of Yosemite

[lemdog_00_98]

I was running mavericks perfect and followed the guide to remove the strings from the bootlist as well as the GenericUSB file. After successful installation, I boot to the HD and it gets stuck at Apple logo with no progress at all--even if leaving for a long time (see pic). I've tried tons of boot flags, even nv_disable=1 which seems to work for most and I cannot get the computer to finish installation to run multibeast post installation. Looking for some help (see verbose boot pic as well). Not sure what RTC is, but it gets stuck at that.

System GA-Z68XP-UD3
i7-2700k 3.8 GHZ
16 GB Corsair Dominator memory
Nvidia GTX 650

Any help would be greatly appreciated. Thanks,

Try and boot with -v -f dart=0 nv_disable=1

post verbose screen if hangs again

Edit**

---

add npci=0x3000 to that

I thought that solved my problem, but it hung up again. Looks like something else is going on with the boot process

have you tried adding -x ?

added -x and got the same result.
