boot freezes

["RMD" <rmd@altec.com.ar>]

Hi all.
I have an odd behaviour on a linux system to be used in an embedded system
(no vga, 4 serials)
The problem is:
booting on a standard pc, using syslinux as the loader, with syslinux.cfg as
follows:

    serial 0 38400
    default linux
    prompt 0
    label linux
        kernel=vmlinuz
        append console=ttyS0,38400n8 console=tty0 root=/dev/hdc2 rw

it starts ok, I can read all kernel messages on the attached terminal,
ending with:

    Freeing unused kernel memory: 176k freed
    serial console detected.  Disabling virtual terminals

and then runs Busybox v0.6.2 as init.
the rcS file in /etc/init.d initializes an LCD display, and /etc/inittab
runs an application that writes on that display.
the inittab file is as this:

    ::sysinit:/etc/init.d/rcS
    ::once:myapplication

All works fine on a PC
But when I try this disk (it´s really a flashcard) on a SBC (x86 too) system
(no vga), and attaching a terminal to ttyS0, I can see it loads the kernel,
with all of it´s hardware and initializing messages, and the last message
is:

    Freeing unused kernel memory: 176k freed

and the system freezes forever and ever...
What else can I do to solve this issue? I´m using a 2.4.2 kernel, compiled
with support for serial consoles, (it works ok on a pc...)
May be something related to /dev/console??

Thanx very much
