OK. I don't have any idea any more. I tried to collect more information, but I
move in a circle:

If there is anybody having an idea, here my today's summary:
Mainboard: Intel DZ87KLT-75K
CPU: Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz

I'm using the internal grapic, I don not have another grafic adapter installed.

The system runs since 2014 with Ubuntu 14.04 and 16.04 without any (obvious)
There is one partition in the system I want to install 18.04. On this partition
I can install 16.04 without any problem. I did so several times and used the
system each for a couple of hours just to see: It works.

Because 18.04 is not even starting the installation process from DVD or USB, I
- Ubuntu 18.04 (mesa 18)
- Debean 9 (mesa 13)
- lubuntu 18.04
- suse 15 Leap with
  - Gnome X11
  - Gnome Wayland
  - KDE
- Ubuntu 16.04 --> dist-upgrade to 18.04. Seemed to run, but cashed as well
after booting the first or second time. (I don't remember)

Sometimes I do have the /sys/class/rdm/card0/error, sometimes not. But I always
see the system crashing in graphic mode. It always runs fine in terminal mode.

Im long anough with linux to know, that there is very often a mystic
swith/parameter/anything to use to overcome the quaintest things.

So don't hesitate to teach me one more. :-)
As you can see I did a lot. If you want me to do more, please advise.
