Installing under z/VM leads to the same failure.

Looks like all ubuntu 18.04 installations on s390 are not working any more.
It is not an issue with z14 but z17 also fails to run a fresh installed
ubuntu 18.04.

when I use the 'advanced installation' where I am able to choose the kernel
package and then choose the 4.15.0-50 generic the installed Ubuntu 18.04 comes
up fine. So this issue is somewhere between kernel 4.15.0-50 and 4.15.0-194.
