[SOLVED] Kernel 4.4.4 on SkyLake Video

Hi all,
today I make pacman -Suy and update the kernel, but again after restart only blank screen. I have the same problem with 4.3.2 - blank screen after the update and after some discussions here in the forum I decide to wait for the next version with hope they fix this problem.
Can someone explain me what happens, and why?

So here is some info about the system:
Arch Linux - Kernel 4.2.5-1 with XFCE4
CPU:Intel® Core™ i7-6700HQ Processor with  Intel® HD Graphics 530
GPU: Nvidia GTX960M

My xorg conf

cat /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
    Identifier             "Monitor0"
EndSection

Section "Device"
    Identifier             "Intel Graphics"
#    Driver                 "vesa"
    Driver                 "intel"
#    Option "Backlight"     "asus-nb-wmi"
    Option "Backlight"     "intel_backlight"
#    Option "NoAccel"       "True"
EndSection

Section "Screen"
    Identifier             "Screen0"  #Collapse Monitor and Device section to Screen section
    Device                 "Device0"
    Monitor                "Monitor0"
    DefaultDepth           24 #Choose the depth (16||24)
    SubSection             "Display"
        Depth              24
        Modes              "1920x1080" #Choose the resolution
    EndSubSection
EndSection

My boot params

cat /boot/loader/entries/arch.conf
title 	Arch Linux
linux	/vmlinuz-linux
initrd	/initramfs-linux.img
options	root=/dev/sdb5 rw acpi_backlight=vendor i915.preliminary_hw_support=1 intel_pstate=disable reboot=pci

sudo pacman -Qe | grep intel
libva-intel-driver 1.6.2-1
xf86-video-intel 1:2.99.917+519+g8229390-1

I've tried without any boot params only with acpi_backlight=vendor i915.preliminary_hw_support=1 only with acpi_backlight=vendor and only with i915.preliminary_hw_support=1, when I was with 4.4.4 but again blankscreen.
If you will need any other info please ask. I wanna upgrade because sometimes the system just freezes. I've add the intel_pstate=disable and the freezes didn't happens so ofthen but still happens lets say 2 times for a week.

p.P.: I have blacklisted this:

cat /etc/modprobe.d/nouveau_blacklist.conf 
blacklist nouveau

Re: [SOLVED] Kernel 4.4.4 on SkyLake Video

Is the black screen when you try to start X or at a console?
What is in the journal from a boot with the 4.4 kernel without i915.preliminary_hw_support=1
Disabling modesetting may help with the blackscreen at console but may prevent Xorg from functioning.

Re: [SOLVED] Kernel 4.4.4 on SkyLake Video

Right after i select Arch Linux, cause I'm dual booting with Windows 10, it goes blank.
I've try with nomodeset and i915.modeset =0 but it freezes again, this time with this code

:: running early hook [udev]
starting version 228
:: running hook [udev]
:: Triggering uevents....

And nothing else happens, I wait 20 min on this screen and nothing.

Re: [SOLVED] Kernel 4.4.4 on SkyLake Video

If you blacklist the i915 module on the command line.Blacklisting using the kernel command line  Does that allow the boot to succeed?
The journal from some of these failed boots should hopefully provide more information.

Re: [SOLVED] Kernel 4.4.4 on SkyLake Video

I've blacklisted i915 but no result, it freez at

:: running early hook [udev]
starting version 228
:: running hook [udev]
:: Triggering uevents....

Can I install only the Nvidia driver and try again to update the kernel. But I'm not sure what method to try Nvidia Optimus // Bumblebee or just Nvidia. I have no problem to use only the Nvidia because I only use the Arch for programming and the laptop is always on AC. For that I read in the wiki I can uninstall the Intel and fallow this article  Nvidia and hope have no problems Please if I'm wrong correct me and redirect me to some other wiki page or forum to try install the Nvidia without a problem

Re: [SOLVED] Kernel 4.4.4 on SkyLake Video

Sorry for the late respond but the problem is resolved when used only

acpi_backlight=vendor idle=nomwait 

in my kernel parameters.
It will be good someone to explain why with this parameter ( idle=nomwait )  their is no problem
