	After upgrading from 6.4 to 6.5, our serial console configuration non
longer work. We have the following upstart file:

[cwfox at hilo ~]$ cat /etc/init/ttyS0.conf
# ttyS0 - agetty
# This service maintains a agetty on ttyS0.

stop on runlevel [S016]
start on runlevel [23]

exec agetty -h -L -w /dev/ttyS0 115200 vt100
[cwfox at hilo ~]$

	And the following in /etc/securetty:

[cwfox at hilo ~]$ sudo tail -2 /etc/securetty
[cwfox at hilo ~]$

	And finally this is appended to what used to be the kernel (now the
module) line in /boot/grub/grub.conf:

module /vmlinuz-2.6.32-431. ro
root=/dev/mapper/vg_hilo-lv_root intel_iommu=on rd_NO_LUKS
LANG=en_US.UTF-8 rd_LVM_LV=vg_hilo/lv_swap rd_NO_MD
SYSFONT=latarcyrheb-sun16 rd_LVM_LV=vg_hilo/lv_root  KEYBOARDTYPE=pc
KEYTABLE=us rd_NO_DM rhgb quiet crashkernel=auto console=tty0

	We've tried putting console=tty0 console=ttyS0,115200 in the kernel
line, but no joy.

	We couldn't find anything in the Release Notes about a change in the
serial console config. Can anyone point us in the right direction please?
