Thanks for your help.
I have installed
root@s8360046:~/linux-4.15.0/tools/perf# uname -a
Linux s8360046 4.15.0-54-generic #58-Ubuntu SMP Mon Jun 24 10:54:05 UTC 2019 s390x s390x s390x GNU/Linux
root@s8360046:~/linux-4.15.0/tools/perf#
and download the corresponding linux kernel source tree from us.ports/ubuntu.com.
So the linux kernel I am using matches the sources and I built the perf tool.
I can also recreate the issue and I start debugging this issue.
