This is inside a qemu ppc64 instance wherein attempting to use POWER9
or the POWER8 cpu types. Seems to result in a kernel panic repeatedly :

Debian GNU/Linux bullseye/sid enceladus hvc0
enceladus login:
I am going to try building a newer QEMU revision ( or maybe use the
version from sid ) and try again. The installed image used for this
was debian-10.0-ppc64-NETINST-1.iso from 2019-11-24.
Also when running with a POWER9 cpu mode I could never use apt-get
due to :
[ 69.338816] apt-get[407]: illegal instruction (4) at 7fff8a3a2b48

All very interesting and again I will build a newer QEMU and try all
this again.
