Hello Harald,
thanks for the report.
The problem you encountered is likely due to a bug where the code doesn't work
on machines with less than 4 physical CPU cores. It is fixed by this patch
series:
https://lore.kernel.org/lkml/20200416054745.740-1-ggherdovich@suse.cz/
The series has been acknowledged by the subsystem maintainers but not yet
merged in any tree (it is expected to land in the "tip" tree and then be pulled
by Linus).
Thanks,
Giovanni Gherdovich

Thanks!
I just sent a new bug report, since rc2 has the same problem. You may
disregard that one, then.
