[Bug 1048611] [NEW] Setting language causes invalid memory access

[ojordan]

Public bug reported:

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 .
