I don't have a good idea what the cause of that would be. I don't think I saw anything similar under qemu's mac99 model. Is there any chance you could dump the `available` property of the /memory node before grub is loaded? I don't think it's likely to be very revealing but it's my best idea so far... I've also since left IBM so I'm not likely to have a heap of time to follow it up, unfortnately. The patch does solve a real issue on Power systems, so I guess the next best thing if we can't root-cause it is to make the link address compile-time configurable :/ Kind regards, Daniel ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

I gave it a try now and made sure to use the proper grub-core directory and that the kernel.img in /usr/local/lib/grub/powerpc-ieee1275/ is up-to-date, so installation went without an error message: root@ibook-g4-14:/home/glaubitz/grub# grub-install -d ./grub-core --macppc-directory=/boot/grub --no-nvram Installing for powerpc-ieee1275 platform. grub-install: warning: cannot open directory `/usr/local/share/locale': No such file or directory.

I saw a similar issue when I only updated the kernel (Makefile.core.def) and not the utils and fixed it with the change to offsets.h. Interestingly you're seeing the issue in reverse: the tools are expecting the new offset but /usr/local/lib/grub/powerpc-ieee1275/kernel.img is built with the old offset. Could you humour me and: - check that your kernel.img in /usr is indeed up to date - try grub-install ... -d ./grub-core? Many thanks!
