[Bug 1990824] Re: initramfs-tools: out-of-memory failures during autopkgtest

[Andrea Righi]

All the initramfs-tools autopkgtest tests seem to run fine on a recent
kernel (5.19) with the debdiff in attach applied.

Title:
  initramfs-tools: out-of-memory failures during autopkgtest

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  [Impact]

  Some autopkgtest tests are failing due to out-of-memory conditions,
  especially amd64-ata-only and net.

  It seems that we are creating a VM with 1GB only to run the amd64-ata-
  only test and even just 512MB for the net test.

  It probably makes sense to create larger VMs (at least 2GB) to run
  these tests with a more recent kernels (that will likely require a
  little more RAM).

  [Test case]

  sudo autopkgtest . -- null

  [Fix]

  Increase memory size of instances used to run the autopkgtests to 2GB.

  [Regression potential]

  We may experience regressions in small cloud instances, or systems
  with less than 2GB or RAM that are using a recent kernel (but this is
  more a generic potential regression, not strictly related to
  initramfs-tools).
