[Bug 1859478] Re: Use the 5.3 kernel for the raspi3 bionic 18.04.4 images

[Launchpad Bug Tracker]

This bug was fixed in the package livecd-rootfs - 2.525.39

---------------
livecd-rootfs (2.525.39) bionic; urgency=medium

  * Ensure seed partition is mounted on no-cloud images which use system-boot
    as their seed (LP: #1860046)
  * Have getty wait for cloud-init to complete to ensure that the default
    user exists before presenting a login prompt

livecd-rootfs (2.525.38) bionic; urgency=medium

  * Support generating a .disk/info file via ubuntu-image from the passed-in
    datestamp parameter (using the $NOW environment variable). (LP: #1856684)
  * Switch raspi2-hwe-18.04-edge to raspi2-hwe-18.04. (LP: #1859478)

livecd-rootfs (2.525.37) bionic; urgency=medium

  * Use the raspi2-hwe-18.04-edge kernel flavour for the raspi3 images. This
    kernel is required for proper pi4 support. (LP: #1859478)

  Use the 5.3 kernel for the raspi3 bionic 18.04.4 images

Bug description:
  [Impact]

  Currently our bionic images only support the pi2, pi3 and cm3 families
  of devices. For 18.04.4 we would also like to enable support for the
  pi4 (available in eoan+). For this to work, kernel support is required
  - this can be achieved by either backporting all the needed pi4
  patches to the 4.15 kernel *or* using the 5.3 raspi one from focal
  that has already been tested and working. We decided that using 5.3 is
  the smartest and safest bet, so for this to work we need to use a
  different kernel flavour - linux-raspi2-5.3.

  This requires a change in livecd-rootfs to pull in the new kernel
  flavour for our raspi3 images.

  [Test Case]

  Build a raspi3 classic bionic image via cdimage with -proposed
  enabled. Confirm that linux-raspi2-5.3 is used instead of linux-
  raspi2.

  [Regression Potential]

  None really. The only thing that could go wrong is that the raspi3
  images would be using the wrong kernel - but that would fail
  verification then.
