No, it's the same kernel. See the cat /proc/version output in the
previous logs.

Actually, it was the OS trying to fetch 'ls' from the filesystem that
returned EIO. 'ls' doesn't run at all. Using the following:-

cd /bin
./<TAB><TAB>

to have the shell's auto-completion list the directory contents, 'ls'
is missing. When trying to manually create the link to busybox, it
claims 'ls' already exists. So I create it in /usr/bin instead and then
'ls' works as expected.

It is symlinked to /proc/mounts

I'll need to set the debug level early at boot since the EIO errors
come from the system failing to load 'ls' not the 'ls' executable
itself.
