At amstan's request I created a new root filesystem without casefold,
and created a loop device with casefold enabled. I am able to boot
with that filesystem.

zgrep UNICODE /proc/config
CONFIG_UNICODE=y
CONFIG_UNICODE_UTF8_DATA=y
CONFIG_UNICODE_NORMALIZATION_SELFTEST=m

mount /dev/loop0p1 /mnt
[ 679.358591] EXT-fs (loop0p1): can't mount with superblock charset:
utf8-12.1.0 not supported by the kernel. flags: 0x0
mount: /mnt: wrong fs type, bad option, bad superblock on
/dev/loop0p1, missing codepage or helper program, or other error.

So it seems I can produce the same error after boot that we saw in
early boot, which makes debugging much easier.

Given that is there anything I should be trying / looking for?
