Closed - P9X79 install stopped [ pci configuration begin ]

Hello everybody,

I read this website since many years and this is for me my third hackintosh ( 1rst Gigabyte EP45-DS3R+Q9400+Gfx 8800GTX 512, 2nd Asus P7P55+i5 750+HD5850 ). For the first time I have a big problem and can't success.

My new config is this one:
Asus P9X79
Xeon E5 2670v1
16Go DDR3 1600
MSI R9 280X 3Go

My install USB stick is the same I used for my old workstation. When I boot to install with my USB stick, it work without problem (only need to use -v PCIRootUID=0 npci=0x2000 GraphicsEnabler=No cpus=1 ). The install process is OK and restart. When I boot again with my USB key on my HDD, my launch is stop at this current line: [ pci configuration begin ].

I try to boot with:
-v cpus=1
-v cpus=1 GraphicsEnabler=No
-v cpus=1 GraphicsEnabler=No PCIRootUID=0
-v cpus=1 GraphicsEnabler=No PCIRootUID=1
-v cpus=1 GraphicsEnabler=No PCIRootUID=0 npci=0x2000
........

I have no more idea. Is there someone who can help me?
Many thanks.

I tried to boot with only -v ( without cpus=1 ) , and the error change. Now I have:
Pthread support ABORTS when sync kernel primitives misused

Do you have any suggest?

I decided to change my target. My mavericks desktop need to be refresh. I start an ElCapitan install.
