The issue seems to be related somehow to systemd's systemd- rfkill.service. When fake-rfkill is loaded, the following message are logged on syslog:

And the call to 'mcli radio wifi' intermittently fails to report that the device is disabled after the call to 'rfkill block $fake_id'. Stopping systemd-rfkill.socket and systemd-rfkill.service units seems to work around the issue since I can't reproduce the issue when they are stopped. As an additional note, I cannot reproduce the issue on the ppc64el host, only on the qemu/kvm guest. -- 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/1733321 Title: network-manager ADT tests fail with on ppc64el with artful/linux 4.13.0.17.18 Status in linux package in Ubuntu: Triaged Status in linux source package in Artful: Triaged Bug description: ppc64el ADT log: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-artful/artful/ppc64el/n/network- manager/20171120_100719_28642@/log.gz Testcase output: ----- autopkgtest [10:04:48]: test killswitches-no-urfkill: [----------------------- make -C /lib/modules/4.13.0-17-generic/build KBUILD_SRC=/lib/modules/4.13.0-17-generic/build M=/tmp/autopkgtest.yE1hsA/build.62e/src/debian/tests make[1]: Entering directory '/usr/src/linux-headers-4.13.0-17-generic' AR /tmp/autopkgtest.yE1hsA/build.62e/src/debian/tests/built-in.o CC [M] /tmp/autopkgtest.yE1hsA/build.62e/src/debian/tests/fake-rfkill.o Building modules, stage 2.
