Re: Xserve G5 OpenFirmware 'CLAIM failed' after dist-upgrade

Thank you for the quick reply, Simon!

Sorry if I wasn't clear but the OpenFirmware is no longer able to 
execute GRUB2 (a PPC32 ELF), after upgrading it. The kernel is loaded by 
grub, and the kernel then loads the initramfs (AFAIK anyway, it's not 
already placed in addressable memory like ARM does with uboot).

But this gives me troubleshooting ideas, I can maybe boot the kernel via 
Ethernet/BOOTP instead, which would help confirm it's GRUB.
