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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927076 Title: IPv6 TCP in reuseport_bpf_cpu from ubuntu_kernel_selftests/net crash P8 node entei on 5.8 kernel (Oops: Exception in kernel mode, sig: 4 [#1]) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1927076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
