[Bug 486051] [NEW] Console redirection does not display kernel messages on screen

[Eward Schippers]

Public bug reported:

Binary package hint: grub2

I followed the instructions for setting grub output to both the console (tty0) and serial (ttyS0)
However grub is giving no kernel message output on the console but is giving the correct output onthe serial console.
Below is my /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX_DEFAULT="quiet console=tty0 console=ttyS0,115200n8"

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=serial
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"

I tried GRUB_TERMINAL=serial console but grub wouldn't accept that.

In short on the screen it skips all the kernel messages and goes from
grub loading directly to login prompt instead of outputting to both
devices.
