Bootable Live CD/DVD Kernel Panic

Good day from Singapore to all Linux users,

Recently, on 12 March 2020, I have successfully created my own custom 
Linux distribution which I affectionately call it Teo En Ming Linux.
My custom Linux distribution is based on the most basic Linux From 
Scratch (LFS) 20200302-systemd book and Linux kernel 5.5.7. I am able to 
boot it successfully on
my Toshiba 1 TB 3.5 inch SATA internal harddisk /dev/sdb2.

After the initial success, I wanted to make a bootable Live CD/DVD of my 
Linux From Scratch system. I followed Jimmy Anderson's guide (which was 
written more
than 7 years ago on 20 Jan 2013) and modified his guide in trying to 
make it work with LFS 20200302-systemd book.

You may refer to the following guides on how I created a bootable Live 
CD/DVD of my Linux From Scratch system.

Scratch (LFS) build"

Filesystem"

When I booted up my bootable Live CD/DVD, I got a kernel panic.

Looking at the following screenshot, it seems that my 64-bit Live CD 
booted in 32-bit mode.

Notice the "trampoline_32bit" and "booted via startup_32()" lines on
the 
above screenshot.

The following screenshot illustrates the kernel panic.

My guess is that my 64-bit Live CD booted up in 32-bit mode, and when it 
tried to execute /sbin/init (symlink to systemd binary) after mounting 
the squashfs root file system, which is 64-bit, it resulted in a kernel 
panic. What I am trying to say is that the 64-bit Linux kernel on the 
Live CD boots up in 32-bit mode (my guess), and then tried to execute 
purely 64-bit binaries, which results in a kernel panic.

Please advise me on how I can resolve this issue and produce a working 
Live CD of my LFS system without kernel panic.

Thank you very much.
