dmesg i915.preliminary_hw_support=1  4.3-rc7

Hi,
i'am trying to make my brand new computer to work with Fedora22 and latest
kernel.
I've install latest intel graphic firmware from 01.org 

dmesg show a lot of i915 errors (see attached file).

To make the graphical desktop working i have to configure my bios as follow: 
IGD (Internal Graphic Display) / 256Mo 

And to boot with kernel parameter i915.preliminary_hw_support=1

I have tried to set the bios to PEG/Multi Monitor (which works but also freeze
sometimes with fedora kernel kernel-4.1.10-200.fc22.x86_64
kernel-4.2.3-200.fc22.x86_64). This bios configuration doesn't work (system
hang on GDM) with 4.3-rc5/6/7

When the system is frozen, i couldn't switch to any VT (eg ctrl-alt F3), even
the reset button wired to my motherboard doesn't work.

When the system "work" with new firwmare i can switch to VT (whereas without it
it was not possible).

I provide you some info and the output of dmesg, tell me if you need more.
I'll try to also add dmesg output with drm.debug=14
