** Description changed:
+ The CONFIG_NLS_ASCII was already set to Y in the raspi-5.4 kernel
+ and bionic kernel by Juerg, now do the same change in the
+ raspi2-5.3 kernel.
+
+ [Impact]
+ users reported that the raspi ubuntu core has some problem to mount
+ filessytem, need to enable the NLS_ASCII and make it built-in.
+
+ [Fix]
+ change it from m to y just as the focal and bionic raspi kernel.
+
+ [Test Case]
+ building the kernel and boot the kernel, it could mount the
+ filesystem successfully.
+
+ [Regression Risk]
+ Low, just changing a kconfig to y from m.
+
+
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. It needs to be set to either 'm' or 'y'. Most of the other
chips have it set to 'y', keeping it built-in.
** Also affects: linux-raspi2 (Ubuntu Eoan)
