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.

Hello Łukasz, or anyone else affected,

Accepted livecd-rootfs into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/2.525.37 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 and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. 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.

As per the build log of https://launchpad.net/~ubuntu-cdimage/+livefs/ubuntu/bionic/cpc/+build/199296, it can be seen that the build pulls in linux-raspi2-hwe-18.04-edge for the kernel - so this seems to work as expected. So at least this part of the new pi support is good to go.

This is still verified, as seen in the latest raspi3 bionic daily build:
