Your boot parameters do not match your kernel .config.  For example,
you cannot specify console=ttyS0 at boot time unless also you built the
kernel with a serial console.  Check your boot time options against
your .config.  My boot has "console=tty0 console=ttyS0,38400" and
.config has

CONFIG_VT=y
CONFIG_VT_CONSOLE=y		(for console=tty)
CONFIG_SERIAL=y
CONFIG_SERIAL_CONSOLE=y		(for console=ttyS0)
