Hi Steve, The node was deployed by our MaaS, we don't build the kernel before testing.
This was tested manually in two ways: A. with the autotest framework: git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests -b master-next git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest rm -fr autotest/client/tests ln -sf ~/autotest-client-tests autotest/client/tests AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_qrt_apparmor/control B. Run the python script directlｙ # Enable deb-src sudo apt-get install -y apparmor apparmor-profiles apparmor-utils apport attr devscripts execstack exim4 gawk git libapparmor-dev libapparmor-perl libcap2-bin libcap-dev libdbus-1-dev libgtk2.0-dev libpam-apparmor netcat pyflakes python3 python3-all-dev python-libapparmor python-pexpect quilt sudo gcc git clone --depth 1 https://git.launchpad.net/qa-regression-testing cd qa-regression-testing/scripts sudo ./test-apparmor.py I tried several times on this and another KVM instance, it's 100% reproducible for a fresh node with either method A or B (it looks like the test will pass on second run, not sure if it has anything to do with the test setup process) Steps: 1. Run the test either with A or B 2. Reboot Everytime when this test hang, it will stuck at the mmap test with operation="profile_load" This hang (timeout) issue can be found on Azure kernel as well: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1763002 The zombie process is affecting the automation. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1783922 Title: ubuntu_qrt_apparmor will hang with Bionic kernel on KVM instance Status in QA Regression Testing: New Status in linux package in Ubuntu: Confirmed Bug description: This test will timeout on a KVM instance (1G ram) with Bionic kernel.
