I am sorry, but that general place complaint is not appropriate here. I can 
provide all information that is needed or requested. I just do not claim 
having done all the tedious and repetitive work my own. If that hero does not 
want to subscribe to the list and make himself known, please respect it. We 
do not seek help here, but want to indicate a problem to help others.

There was a system running (SL6.x, depending on which of the three test 
machines it happened). However, on the new disk there was no partition table 
(as explained). We did not want to overwrite anything of the precious old 
configuration. And the only change between "Hangs somewhere in installation 
with dark screen and (moving) mouse pointer" and "works" was to "fdisk" just 
one dummy partition on that new disk.

I cannot remember the spoke and wheel GUI upstream. Do you mean the new 
interface for partitioning, which is already in service on Fedora 22 for 
example? I know that, but I do not see your point or the relationship to our 
problems.

Why? What exactly do you think we need to understand? There was no possibility 
(at least not visible enough) to partition the new disk during the 
installation procedure. We guessed the reason and managed to partition it on 
another system manually (gparted).

As a conclusion, I understand there is no requirement to have a 
pre-partitioned disk for installation (as expected and reasonable). Thanks. 
Can anybody reproduce the problem? We did it three times on different systems. 
And yes, if time allows I will try to reproduce it on a VM installation, but I 
am afraid VM disks (on VirtualBox) are or "look to the installer like" 
pre-partitioned disks anyway.
