Perhaps looking backward from this Raspberry pi kernel will help locate the issue, which was definitely present in the build below:
5.3.0-1026-raspi2 #28~18.04.1-Ubuntu SMP Thu May 21 14:48:58 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux The final kernel that was getting built on arm64 did not have the flag set on that tag. The same flag is notably absent in the arm64 defconfig, which appears to be what was used judging from the buildlog output I was able to see searching on that tag. If this was very recently fixed, we haven't received a snap refresh as of yet. -- Brent DeGraaf Principal Engineer 734.395.0852 brent.degr...@k4connect.com [image: image.png] www.K4Connect.com <http://www.k4connect.com/> | @K4Connect <https://twitter.com/K4Connect> | Facebook <https://www.facebook.com/k4connect>| LinkedIn <https://www.linkedin.com/company/5187480> 5511 Capital Center Dr. Suite 350 Raleigh, NC 27606 On Tue, Jun 2, 2020 at 11:45 AM Loïc Minier <1881...@bugs.launchpad.net> wrote: > ubuntu-focal.git, focal/raspi2 branch: > debian.raspi2/config/config.common.ubuntu:CONFIG_NLS_ASCII=y > > ubuntu-bionic.git, bionic/raspi2 branch: > debian.raspi2/config/config.common.ubuntu:CONFIG_NLS_ASCII=y > > So not quite sure where this is coming from > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1881631 > > Title: > arm64 Ubuntu kernel builds missing CONFIG_NLS_ASCII > > Status in linux-raspi2 package in Ubuntu: > Confirmed > > Bug description: > Remounting log mounts in Ubuntu core are failing on arm64 builds due to > missing CONFIG_NLS_ASCII in the arm64 kernel build options. > This option is enabled on the other kernel builds but somehow was > overlooked on arm64 appears to affect our ability to access logs via > journalctl with data from prior to restart because certain mounts are > failing. > Other Raspberry Pi kernel builds, such as the armhf build, have the > option enabled and so do not encounter the mount error. > The kernel option that needs to be turned on to resolve this is > CONFIG_NLS_ASCII.

This option is enabled on the other kernel builds but somehow was overlooked on arm64 appears to affect our ability to access logs via journalctl with data from prior to restart because certain mounts are failing. Other Raspberry Pi kernel builds, such as the armhf build, have the option enabled and so do not encounter the mount error. The kernel option that needs to be turned on to resolve this is CONFIG_NLS_ASCII. It needs to be set to either 'm' or 'y'. Most of the other chips have it set to 'y', keeping it built-in.
