[Bug 1992178] Re: autopkgtest: upstream tests that run in qemu hang on ppc64el

[Launchpad Bug Tracker]

This bug was fixed in the package systemd - 251.4-1ubuntu7

---------------
systemd (251.4-1ubuntu7) kinetic; urgency=medium

  [ Nick Rosbrook ]
  * autopkgtest: do not allow qemu to be used on ppc64el (LP: #1992178)
    Almost every run on ppc64el takes 12 to 24 hours, so do this as a last
    resort to relieve pressure on autopkgtest infrastructure.

Title:
  autopkgtest: upstream tests that run in qemu hang on ppc64el

Status in systemd package in Ubuntu:
  Fix Released

Bug description:
  I believe this started early in the kinetic cycle, cf.
  https://autopkgtest.ubuntu.com/packages/systemd/kinetic/ppc64el vs
  https://autopkgtest.ubuntu.com/packages/systemd/jammy/ppc64el.
  Timeouts in the upstream tests have been an issue for a while, but
  kinetic on ppc64el consistently times out with upstream tests that run
  in QEMU.

  Skipping individual tests does not help, because *which* tests time
  out appears to change with each build. For example, in 251.4-1ubuntu4
  the TEST-36-NUMAPOLICY test was consistently the culprit, but now in
  251.4-1ubuntu6 the TEST-14-MACHINE-ID often times out.

  I have not been able to identify a root cause for this, but it seems
  that running tests in QEMU is very fragile on ppc64el, where as the
  tests that run in nspawn are more consistent.
