It looks like this hang issue was introduced because the mmap test has timed out. And it gets killed by the autotest framework.
However it's not really "killed", you can see that it's still stuck with mmap test: # ps aux root 23787 0.0 0.0 4384 748 ? S 06:21 0:00 /tmp/testlibpIXHkr/source/bionic/apparmor-2.12/tests/regression/apparmor/mmap # ps aux |grep Z USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND ubuntu 2138 0.0 0.0 0 0 ?

Z 10:15 0:00 [unix_socket_cli] <defunct> In this case, with PID 23787 killed, the test will keep going and terminates on jenkins properly. -- 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 (mmap test timeout) Status in QA Regression Testing: New Status in linux package in Ubuntu: Triaged Bug description: This test will timeout on a KVM instance (1G ram) with Bionic kernel.
