"bin/sh: can't access tty; job control turned off” error when running shellcode"

Just remove /dev/console

cd /dev
rm -f console
ln -s ttyS0 console

edit/change the /etc/inittab content

::askfirst:/bin/sh

to:

ttyS0::askfirst:/bin/sh

If you can change the command of the shell, try:sh +m instead of sh. That worked perfectly for me.
