Hi Marius,

The output shown looks like the ubuntu-text splash screen.  Since your
kernel command line doesn't show the 'splash' option, this should only
happen if you pressed Esc during boot.  Did you?  (Otherwise, the
'details' theme should have been used, which just displays the console
text.)

Do you have an 8-bit clean serial console here?  I would generally
expect this text to display correctly on a serial console just as on the
standard console, unless configuring/using a wrong terminal emulator or
using a serial console that filters the output.

Title:
  plymouth: broken output on serial console (screen full of
  [-1;-1fUbuntu 10.04)

Status in “plymouth” package in Ubuntu:
  Incomplete

Bug description:
  Lucid 10.04.3 LTS, plymouth 0.8.2-2ubuntu2.2.

  I rebooted the server while connected to the serial console of the integrated remote management card (HP iLO 2; basically, ssh servername-ilo, type VSP, observe the contents of ttyS1 relayed to my gnome-terminal).  After a few fsck messages I got this:
  (see attachment).

  When fsck finally finished (filling up several screens with
  "?[-1;-1fUbuntu 10.04?[-1;-1f. . . .?[-1;-1fUbuntu 10.04?[-1;-1f. . .
  .", where the ? stands for a little box drawing of a missing font
  glyph with code U+001b), I got my login prompt (from a custom
  /etc/init/ttyS1.conf that was based on /etc/init/tty1.conf, with just
  the device name and speed changed).

  The login prompt was in bright grey on white.  Basically invisible.

  Extra information:

  * /boot/grub/menu.lst has "# defoptions=console=tty0 console=ttyS1,115200n8"
  * /proc/cmdline contains "root=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx ro console=tty0 console=ttyS1,115200n8"
  * /etc/init/ttyS1.conf contains

      start on stopped rc RUNLEVEL=[2345]
      stop on runlevel [!2345]
      respawn
      exec /sbin/getty -8 115200 ttyS1
