Subject: Teo En Ming's Linux From Scratch (LFS) 20200302-systemd
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.

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.
