Can you repeat tests with latest kernels? I could not reproduce it on Focal with following configurations:
1. Power8: P8LPAR05 MAAS
2. Power9: QEMU with 4 or 128 CPUs (and 4 GB of RAM)

Tested kernels:
F/5.4.0-84-generic
F/5.11.0-34-generic

Tried steps:
1. Freshly boot machine.
2. Log in via ssh.
3. sudo ./autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/cpu-hotplug/cpu-on-off-test.sh

4. for i in `seq 100`; do echo $i ; sleep 2 ; sudo ./autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/net/reuseport_bpf_cpu ; done
