Title: ADT tests fail since 4.11.0-11.16 Status in linux package in Ubuntu: Triaged Bug description: The ADT tests started failing with 4.11.0-11.16 on amd64, i386 and ppc64el: all the arches we run using qemu over OpenStack. The virtual machines hang completely. The last lines in the log are: 12:11:18 DEBUG| [stdout] Test icebp [Ok] 12:11:18 DEBUG| [stdout] Test int 3 trap [Failed] 12:11:18 DEBUG| [stdout] selftests: breakpoint_test [PASS] 12:11:18 DEBUG| [stdout] /tmp/autopkgtest.zKFdZm/build.ham/linux-4.11.0/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/breakpoints ... and on the console we see a lot of messages like: ** 35 printk messages dropped ** [ 3577.683828] ACPI Error: No installed handler for fixed event - SleepButton (3), disabling (20170119/evevent-286) ** 33 printk messages dropped ** [ 3577.686564] ACPI Error: Could not disable RealTimeClock events (20170119/evxfevnt-267) ** 25 printk messages dropped ** [ 3577.688566] ACPI Error: No installed handler for fixed event - SleepButton (3), disabling (20170119/evevent-286) ** 35 printk messages dropped ** [ 3577.692788] ACPI Error: No installed handler for fixed event - SleepButton (3), disabling (20170119/evevent-286) ** 29 printk messages dropped ** [ 3577.695184] ACPI Error: No installed handler for fixed event - SleepButton (3), disabling (20170119/evevent-286) ** 34 printk messages dropped ** [ 3577.697955] ACPI Error: No installed handler for fixed event - PM_Timer (0), disabling (20170119/evevent-286) I've attached the full log. In the log file there is the invocation I used to generate the failing log. You should be able to try similar using either `qemu' locally. If that doesn't reproduce, try on Canonistack. If *that* doesn't reproduce, apw or I can run test builds for you if there's a PPA to test from. This tickles an unfortunate behaviour in the way we run autopkgtest. What happens is: the machine hangs, autopkgtest notices this has happened, it tries to clean up the testbed and can't get into it because it is hung. This is counted as a 'temporary failure', and so the job is requeued forever. As a result, I've blacklisted linux from the workers. Please reach out to us for manual runs, and then once it is confirmed to not loop in this way we'll remove the blacklist.
