I believe you are running out of memory here because grub is trying to load all those frame buffer modules within your config.

And then it didn’t find one that worked.

For this, I believe you are having the same problem as Frans. Could you add the following to /etc/default/grub:

GRUB_TERMINAL_OUTPUT="console"
GRUB_DISABLE_RECOVERY="true"
GRUB_PRELOAD_MODULES=“iso9660"

and then regenerate your grub.cfg with grub-mkconfig.

Adrian,

I don’t plan on adding frame buffer support since newer systems don’t have them. Would it be possible to change your grub package to include a /etc/default/grub file for SPARC with the changes above? We do the same thing with our grub rpm.
Oh, absolutely. Thanks for the suggestion. This was just the first package and I'm happy to include
all improvements that are necessary.

Adrian

Your menu entry in /etc/grub.d/10_linux still seems to have a load_video function which would do an insmod of
efi_gop
efi_uga
ieee1275_fb
vbe
vga
video_bochs
video_cirrus

if I read it correctly.. not sure you want these.

Adrian
