[Timo Aaltonen]

Hello Roxana, or anyone else affected,

Accepted initramfs-tools into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/initramfs-
tools/0.140ubuntu13.4 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  autopkgtest net is failing on 6.2 kernels with 'System is deadlocked
  on memory'

Status in initramfs-tools package in Ubuntu:
  Fix Released
Status in initramfs-tools source package in Jammy:
  Fix Committed
Status in initramfs-tools source package in Lunar:
  Fix Committed

Bug description:
  [Impact]
  In debian/tests/run-image we instantiate an image with 512Mb of ram, but recent jammy/lunar 6.2 kernels need more than that.

  Example of a test failure:
  https://autopkgtest.ubuntu.com/results/autopkgtest-lunar/lunar/amd64/i/initramfs-tools/20230619_135049_ab1cb@/log.gz

  'net' test fails with a kernel panic due to out-of-memory.

  It also relies on an existing and working cloud image. If the cloud
  image is not available, the test will silently succeed.

  [Fix]

  The net autopkgtest was ported to the common test framework in
  initramfs-tools 0.142ubuntu3. This makes the test more robust by
  relying on the minimum needed for the integration test.

  [Test Plan]

  Check that the autopkgtest succeed or test it manually:

  1. Download a lunar image:
  $ autopkgtest-buildvm-ubuntu-cloud -v -a amd64 -r lunar
  2. Run autotestpkg tests from initramfs-tools package. The "net" test is the one that depends on the image instantiated by 'run-image'. The testcase should complete successfully without the kernel panic.
  $ autopkgtest initramfs-tools -- qemu autopkgtest-lunar-amd64.img

  [Where problems could occur]
  The usage of a larger image for the tests could fail if the the test system is low on ram size.
