[Clover+El Capitan] (X99) Stuck on Grey Screen With Beach Ball

[rohanpatel777]

Problem:
I am using a full Clover install of the app store version of El Capitan for my X99 based system. Everything runs smoothly until the line in the verbose boot:
NVDA: disabled by nv_disable=1 (<-- line occurs 4 times)

After that line, the screen turns grey and the beach ball starts spinning. No response after that .

What I have tried:
1. A whole list of different combinations of GraphicsEnabler and other bootflags related to graphics.
2. Manually extracting and installing Nvidia Web Drivers for the 970 with Pacifist.

Specs:
Intel i7-5820K at 3.4GHz (stock) [corsair h100i cooler] [fractal design define r4 case]
Asus X99-A mobo
Nvidia Gigabyte GTX970 G1
Hitachi 10,000rpm 500gb HDD MAC INSTALL DISK DRIVE
EVGA 80+ Gold SuperNova V2 850 watt
Samsung Evo 850 SSD 500gb (win10 install)

Any Ideas? Thank you so much!

I encountered the same problem (beach ball) when using Clover USB Install method for Yosemite (then upgrade to El Capitan). Using the Unibeast USB installer worked for me, then installing clover for post install (skipping MultiBeast).
