Depending which terminal emulator you're using, you should be able to
turn line wrapping on.

Once you have the line-wrapped error output it will be easier to diagnose.
With some rootfsses I have needed to create /dev/console in the root
filesystem to get round a "Cannot open an initial console" message,
which I think is when init starts up. If it's missing:
(sitting in the root of the fs) # mknod dev/console c 5 1
You don't need a /dev/ttyAM0 entry to get the whoosh of boot messages,
but will need one to get a login prompt on the serial console,
assuming you have hacked etc/inittab to include a line like
S0:23:respawn:/sbin/getty -L 115200 ttyAM0 vt102
and (in the root of the fs):
# mknod dev/ttyAM0 c 204 16
In desperation, you can get a half-working login prompt on the console
by using a line in inittab
co:23:respawn:/sbin/getty -L 115200 console vt102
Not being a proper tty device, it won't support job control and
keyboard-generated interrupts, but might be enough to get the real
thing up and running
