I will try to check if SP operation makes a difference, if I find out
how to disable MP operation, because there doesn't seem to be a SP
kernel available for ppc64. Hence I'm also not 100% sure that the
installer really operates in SP mode. I have to check `/proc/cpuinfo`
during an installation to be sure.
The installer operates in MP mode:
```
~ # uname -a
Linux (none) 4.19.0-2-powerpc64 #1 SMP Debian 4.19.16-1 (2019-01-17)
ppc64 GNU/Linux
```
...and the ipr module is loaded but doesn't make any problems:

Unloading and reloading the module makes no issues, too.
Not sure what makes the difference, well the kernel is a little older
and the list of loaded modules is very short. I have to compare that
with the list of loaded modules when the machine boots with kernel and
initramfs from disk and root FS from network. Maybe there is some
interaction that makes problems.
Cheers,
Frank
