XPS 9350 - panic with 4.4rc3 and i915 firmware

[friimaind]

Hi all,
I have an XPS 13 9350 256GB FHD.
I'm trying to use any 4.4 kernel installed following this guide: http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/

I have added i915 in /etc/initramfs-tools/modules and launched sudo update-initramfs -u -k all

When I select the new kernel in grub I see a black screen and on kernel.log I see

i915 0000:00:02.0: registered panic notifier

Maybe I've done a mistake because, before the reboot, I have installed:

• Intel Graphics Installer for Linux
• skylake-dmc-1.23

Kernel 4.2 boots fine (clearly without wifi)
