Thanks Daiane for your inputs!

The link you pasted indicates that correct serial port must be specified.

I have ensured that correct serial port is set (/etc/inittab) . I can
see the errors but I cannot see the stdout.
I think there is a setting for verbosity, which is set to quiet. I'm
not sure though.

FYI: I also have installed procps package.

I modified the file /etc/init.d/bootmisc.sh:
original line:  eval /sbin/sysctl -p "${SYSCTL_CONF}" $VERBOSE_REDIR
edited line:    eval /sbin/sysctl -p "${SYSCTL_CONF}"
(VERBOSE_REDIR is set to "1>/dev/null")

After the above modification, I can see script stdout while system
reboot or shutdown, but I cannot see the same during system startup.

Any idea what am I missing?

Regards, Pj
