I have the strong suggestion that this is the cause:

commit 6edb63a7b6cd57825e47cf6a8600b694a19f0d90

s390/archrandom: simplify back to earlier design and initialize earlier
BugLink: https://bugs.launchpad.net/bugs/1989625
commit e4f74400308cb8abde5fdc9cad609c2aba32110c upstream.

...

because that's the only patch which has changes in the s390 start kernel/arch/random areas.

Recreate is totally simple: just install a Ubuntu 18.04 - does not matter if it is on LPAR or zVM or as a KVM guest.
If my suggestion is right, this happens since kernel 4.15.0-194.
