--- Comment #58 from David dstansby@gmail.com 2010-12-17 18:03:45 --- New comment downstream saying:

"I've got Ubuntu 10.10 (2.6.35-23-generic #41-Ubuntu SMP) booting using my old grub 1.97 (that was booting Ubuntu 9.04) compiled as so:

./configure --with-platform=efi --target=x86_64 make ./grub-mkimage -d . -o grub.efi acpi boot chain configfile ext2 fat hfsplus normal part_gpt sh

Then my grub.cfg has

menuentry "linux latest" { root=(hd0,3) fakebios linux /vmlinuz root=/dev/sda3 video=efifb agp=off acpi=force initrd /initrd.img }

I've got 2 CPUs, ACPI (sleep, reboot, poweroff, battery/power) - my next step will be to try a newer version of grub2."
