Plasma5 - SDDM black screen after kernel/mesa/xorg update

On my machine running slackware-current and Eric's Plasma5 set of packages, I've upgraded all together kernel-4.4.5, mesa-11.1.2 and xorg-server-1.18.2, and sddm login stopped working.
Booting in runlevel 4 I get only a black screen with blinking cursor on the top-left side of the monitor.
Everithing works flawlessy booting in runlevel 3 and using "startx".
Nothing has changed with the latest "KDE 5_16.03" upgrade.

In /var/log/messages I find lot of

kernel: [  158.167700] traps: sddm-greeter[1367] trap invalid opcode ip:7ffb34613646 sp:7fffac74c8a0 error:0

wile in /var/log/sddm I find

Googling around it seems related to the kernel, does anyone have the same problem?

P.S.: I've a skylake processor.

I did a full upgrade yesterday it went flawless. and I run multi lib.
I skipped two upgrades and did this one.
after downloading the latest stable current 5.
First I upgraded all my slackware and made sure all my sbo-builds would be updated with any new additions.
then this is the script I used. after I uninstalled nvidia.

   slackpkg update
   slackpkg install-new
   slackpkg upgrade-all
   slackpkg install ConsoleKit2
   slackpkg install eigen2
   slackpkg  install xapian-core

   slackpkg re-install ConsoleKit2
   slackpkg re-install eigen2
   slackpkg  re-install xapian-core
   removepkg ConsoleKit
   removepkg grantlee-qt5
   removepkg kgamma
   removepkg pairs
   removepkg LoginKit
   removepkg kdeconnect4
   rsync -r -a -v --bwlimit=200 --delete --progress --stats rsync:// /var/cache/multilib/
   cd /var/cache/multilib
   upgradepkg  --install-new *.t?z
   cd /var/cache/multilib/slackware64-compat32
   upgradepkg --install-new *?/*.t?z
  cd /root/5
 upgradepkg --reinstall --install-new x86_64/deps/*.t?z
 echo deps installed
 sleep 2
 upgradepkg --reinstall --install-new x86_64/deps/telepathy/*.t?z
  echo telepathy installed
 sleep 2
 upgradepkg --reinstall --install-new x86_64/kde/*/*.t?z
 slackpkg new-config
 echo kde installed
then I rebooted with the vmlinuz-huge telinit 3
created an intrid.gz. then I ran my linux setup scripts.
then rebooted with the generic kernel
then rebuilt the latest nvidia.
after logging in the theme manager would not change. so I logged out.
init 3 logged in as root and deleted ~/home/.kde and .config and .cache of my user.
then logged using init 4
signed in as the user and things where ok. The only issue I find is fonts are going blurry they do not seem to refresh at times.
after that I rebuilt all my media ffmpeg vlc patents yes rebuilt pulseaudio so it would use my jackd2 then rebuilt mplayer to use patents yes.
rebuilt my alsa-plugins so they would build against ffmpeg and jack2 and pulse audio rebuilt speex from slackbuilds.
That is my experience.
I only blacklist I have alien and compat32.

Ok, I solved the issue, for reasons that I don't know, "sddm" no longer wasn't in "video" group.
Adding sddm user to the video group did the trick.
