[SOLVED] Kernel update 4.5.4-1 to 4.6.2-1 breaks graphics boot

After updating this laptop today, once the graphical target is reached, the system locks up completely. I can't use Ctrl-Alt to switch to a tty either. Had to hard-reset it.

I know this sounds very similar to https://bbs.archlinux.org/viewtopic.php?id=208652, but I never had any issues until this update to kernel 4.6, so I wonder if this is a different issue altogether? If not, feel free to merge.

Today's update included xorg-server, xorg-server-common and wayland as well, but downgrading those did not fix the issue. It wasn't until I downgraded linux and linux-headers back to 4.5.4-1 everything was working.

I tried capturing Xorg.0.log, but for details, but I only can get successful runs to log. Something's really locked up with this new kernel.

xf86-video-intel 1:2.99.917+654+ga508b11-1

>$ lspci | grep -e VGA -e 3D
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

Edit: I believe this is the same issue as reported in https://bbs.archlinux.org/viewtopic.php?id=213495, with the only change being this is for kernel .2, not .1, but I didn't notice that thread until now.

Final edit: Fixed in kernel 4.7 using the "modesetting" driver (uninstall xf86-video-intel) and setting "options i915 enable_psr=0" in /etc/modprobe.d/i915.conf

The whole Kernel 4.6 and systemd 230 is a mess not working well on all intel baytrail, braswell, haswell, broadwell and skylake plattforms and causing many problems with graphics. Several half-baked workarounds are available but no intelligent solution.
Just use systemd 229 and linux-lts 4.4.13-1 for the moment and avoid updating for now.

And downgrading an avoiding updating is not a "half-baked" workaround?

Try removing xf86-video-intel.  That has been on it's way out for some time and is no longer needed.

I experimented with removing xf86-video-intel, unfortunately doesn't work in my case - I reported my findings in https://bbs.archlinux.org/viewtopic.php?id=213495; probably best if we keep that thread as the place to figure out how we can get this to work.

Thanks for the advise. I had some unexplainable graphics problem, and unfortunately no other solution was found but installing 4.1 LTS kernel.

P.S. BTW, regarding systemd 229:

same as OP here:

i have xf86-video-intel, and since upgrading to 4.6, SDDM freezes after a second or so, and only REISUB helps.

Removing xf86-video-intel is a bad advice as massive tearing appears and libreoffice shows weird rendering issues and empty dialouge boxes.
Everything works wit linux-lts and  xf86-video-intel.

I deleted  /etc/modprobe.d/i915.conf which used to contain

options i915 enable_rc6=1 enable_fbc=1 semaphores=1

and I was able to successfully run XFCE on my netbook.Previously (this morning) my system would panic (blinking CAPS LOCK light; non-responsive MagicSysRq) shortly after firing up the XFCE window manager.

$ pacman -Q linux systemd xf86-video-intel
linux 4.6.3-1
systemd 230-5
xf86-video-intel 1:2.99.917+668+gc28e62f-1

My /etc/X11/xorg.conf.d/20-intel.conf  contains

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"        "true"
   Option      "DRI"		 "3"
EndSection
