Can be reproduced with Eoan LPAR s390x 5.3.0-28-generic. Rate 4 out of 4 attempts. If you ssh to the node, when this happens you will be disconnected. This is why the test got interrupted on jenkins. ** Tags added: sru-20200106 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856163 Title: test_maps test from ubuntu_bpf will cause OOM on Eoan s390x LPAR To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1856163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It looks like the test will trigger OOM, but the autotest gets killed this time. I tried with older 5.3.0-24 kernel, the test_maps passed one time, but the OOM error message can still be seen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856163 Title: test_maps test from ubuntu_bpf will cause OOM on Eoan s390x LPAR To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1856163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
