[Bug 1048611] Re: Setting language causes invalid memory access

[ojordan]

This is what I did to workaround the problem:

sudo nano /etc/grub.d/00_header

Find this bit of code:

# Gettext variables and module
if [ "x${LANG}" != "xC" ] && [ -d "${locale_dir}" ] ; then
    prepare_grub_to_access_device $(${grub_probe} --target=device ${locale_dir}) | sed -e "s/^/  /"
  cat << EOF
  set locale_dir=(\$root)$(make_system_path_relative_to_its_root ${locale_dir})
  set lang=${grub_lang}
  insmod gettext
EOF
fi

You can delete that whole piece of code, but I just commented out the
'insmod gettext' line by putting ### at the start and end of the line:

###insmod gettext###

Save and re-run update-grub or grub-mkconfig:

sudo update-grub

Title:
  Setting language causes invalid memory access

Status in “grub2” package in Ubuntu:

Bug description:
  Hi, I've been experimenting with grub2 on my G4 (PowerPC) iBook.
  Using the grub.cfg generated by the grub-mkconfig command causes the
  following error when booting:

  Invalid memory access at &SRR0: 0020567c &SRR1: 00003030

  Note, I've used a '&' charcter in the above address but it was more
  like a beta or maybe a pi character (very small text on screen).

  Anway, the result is I get dumped back into openfirmware.

  After a lot of reboots I've narrowed the fault down to these two lines
  in the grub.cfg:

  set lang=en_GB
  insmod gettext

  The 'insmod gettext' is what causes the crash.  However, inserting the
  module gettext without setting the language doesn't cause a problem.
  Similarly, set lang=en_GB doesn't cause a problem if you don't load
  gettext.  It is the combination of the two that is the problem (it
  crashes whatever order you do them in).

  I think this chap has the same problem http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=685295 .
